Preface Since the sixties, numerical methods for solving complex multiphysic problems have undergone continuous
improvements thanks to the availability of more and more powerful computers and the development of
interactive robust software based on realistic material behavior and sophisticated algorithms. Like all other
sectors of engineering sciences, the field of material forming simulation or “virtual forming” takes full
benefit from these scientific and technological developments.
The NUMIFORM triennial international conferences series, introduced by the late Prof. O.C.Zienkiewicz in
1982, aim to provide a forum where recent advances and future directions in the numerical simulations of
forming and manufacturing processes are discussed by scientists and engineers from academia and
industry worldwide. The topics covered are of great interest not only for academics from theoretical and
computational mechanics but also for professionals (engineers and researchers) from industry involved in
traditional and novel forming and manufacturing technologies for conventional and emerging materials.
This twelfth edition of the NUMIFORM international conferences series (NUMIFORM2016) is held at
University of Technology of Troyes (UTT) in France from July 4th to 7th 2016, co-organized with two
renowned French companies in the field of virtual forming technologies: ESI Group and Transvalor SA. As
the eleven previous editions of NUMIFORM international conferences series (summarized in the map given
hereafter), this edition provides a forum for scientists and practicing engineers alike to present the latest
findings in their research endeavor and at the same time to explore future research directions in the field.
A total of 205 oral presentations from 33 worldwide countries are registered including:
• Six plenary conferences given by renowned experts (three from academia and three from industry).
• 199 oral presentations organized in 12 mini symposia (MS), 2 general topics (TOPIC 3 and Topic 4)
and two industrial mini symposia (IMS) dedicated to the bulk forming (IMS1) and sheet forming (IMS2).
An industrial exhibition is also organized during the three conference days.
The 199 oral presentations are composed on 105 peer reviewed full papers (between 4 and 8 pages each
one), 71 single reviewed extended abstracts with less than 4 full pages and 24 short abstracts (80 words).
The free access to all these 199 papers will be provided to all the registered attendees. However, the 105
peer reviewed full papers will be published, after the conference, in the open access proceedings by MATEC
Web of Conferences (EDP Sciences) in the area of Mechanics with ISBN and referenced in many databases.
The name of this open access proceedings is: MATECWoC-15-Numiform2016. Some selected full papers
(selection made by the MS organizers) will be invited to be extended and submitted for peer review journal
IJFO (International Journal of Material Forming, ISSN: 1292-7775) after the conference.
We address our warm thanks to all the authors and participants to this twelfth edition of NUMIFORM
international conferences series. In addition, our thanks are due to public and private sponsors who,
through their financial support or their participation to the industrial exhibition, helped significantly the
organization of this event: UTT, ESI Group, Transvalor SA, Région Champagne-Ardenne, Conseil Général de
l’Aube, Grand Troyes, l’Association Française de Mécanique (AFM), MECAMAT, MK2i, Composite Integrity,
QForm. Special thanks are due to the colleagues who organized and fully managed the papers submitted to
their MS/IMS and Tasks, as well as many colleagues from the international Scientific Committee, the
Steering Committee and the Advisory committee who kindly performed the reviewing of some full papers
and/or extended abstracts. Many thanks are due to the colleagues from UTT/LASMIS, ESI Group and
Transvalor SA involved in the practical organization of NUMIFORM2016.

Finally, we give you an appointment in 3 years for the THIRTEENTH edition to be held in 2019
(NUMIFORM2019) which will be officially announced by the steering committee during the banquet on
Tuesday 5 July 2016. During the same banquet, the “O. C. Zienkiewicz award” will be also attributed.

Plenary Lectures
Speaker: Prof. F. Barlat (POSTECH, Republic of Korea) Dr. Barlat is full professor at the Pohang University of Science and Technology (POSTECH) in the Republic of Korea. He is the director of the Material Mechanics Laboratory at the Graduate Institute of Ferrous Technology (GIFT). His research focuses on the development of innovative plasticity theories for metals, as well as forming process and manufacturing technologies for steel products. Professor Barlat is associate editor for International Journal of Material Forming, and Modeling and Simulations in Materials Science and Engineering. He was the chairman of the 10th NUMIFORM conference, which was held in 2010 on POSTECH Campus. He published over 200 articles in peer-
reviewed scientific journals and received a number of awards, in particular, the Khan International Medal for outstanding life-long contributions to the field of Plasticity. Title: Advanced Constitutive Modeling and Application to Industrial Forming Processes Author: F. Barlat (POSTECH) and Dong-Jin Kim (POSCO) Day/Room/Hour: Tuesday/ Room M500/ 13:45-14:25 Abstract: Continuum constitutive descriptions of plasticity suitable for finite element simulations of sheet forming processes are succinctly discussed in this presentation. Although multi-scale approaches allow for a more explicit representation of the physical deformation mechanisms occurring at microscopic scales, they are usually not suitable for industrial applications because of the quick turnaround time needed for process design simulations. Therefore, advances in classical concepts such as plastic anisotropy and strain hardening are still very much in demand. Actual forming simulation examples conducted in the steel industry are presented for illustration purposes.
Speaker: Prof. K.J. Bathe (MIT, Cambridge, USA) Klaus-Jürgen Bathe is Professor of Mechanical Engineering at the Massachusetts Institute of Technology. He teaches and performs research in the areas of applied and computational mechanics of structures, fluids, and electromagnetics. Professor Bathe is also the Founder of the company ADINA R & D, Inc. where he leads the development of the ADINA system, used world-wide, for the analysis of structures, fluids, and multi-physics problems. He has published numerous articles, six textbooks and the book To Enrich Life. He is a co-editor of the international journal Computers and Structures, and the Editor of the proceedings of twelve M.I.T. Conferences on Nonlinear Finite
Element Analysis and seven M.I.T. Conferences on Computational Fluid and Solid Mechanics. He has been honored by the ASME, ASCE, U.S. National Academy of Engineering, M.I.T., and many honorary doctorates for his teaching, his pioneering, fundamental and widely used contributions in computational mechanics, and for bridging the world between Academia and Industry. Title: Advances in finite element methods for the simulation of forming processes Author: K.J. Bathe, MIT Cambridge, USA Day/Room/Hour: Monday/ Room M500 / 09:15-09:55 Abstract: We present some recent advances in finite element methods for the analysis of forming processes. These advances pertain to solid and shell finite elements for large strain solutions, contact analyses, improved explicit and implicit time integration schemes, the analysis of fluid-structure interactions, electromagnetic effects, and the development of "overlapping finite elements". The use of overlapping finite elements promises to be an avenue for very effective analysis schemes. Illustrative solutions are given to show the characteristics of the various methods discussed.
Speaker: Dr. O. Ghouati (Ford Research & Advanced Engineering, Aachen, Germany) Dr Omar Ghouati graduated in 1991 at ENSMM Besancon, France, in Mechanical Engineering, earned his PhD at University of Franche-Comté in 1994.

Title: Stamping simulation at Ford - Challenges and opportunities Author: O. Ghouati, E. Liasi and A. Zaum (Ford) Day/Room/Hour: Wednesday/ Room M500/ 13:45-14:25 Abstract: For high volume production, majority of components of the body in white are stamped. Driven by the pressure to reduce weight, part geometries and materials behaviors are increasing in complexity. It is now usual to use simulation to perform process layout and ensure the try-out phase is kept to the minimum. In this presentation we will give an overview
14
of the use of stamping simulation at Ford. Based on actual cases, limitations and expectations for the simulation will be discussed.
Speaker: Prof. R. Logé (EPFL, Switzerland) Roland Logé graduated in 1994 at UCL, Belgium, in Materials Science Engineering, earned a Master of Science in Mechanics in 1995, at UCSB Santa Barbara (USA), and his PhD at Mines Paristech-CEMEF (France) in 1999. After a postdoc at Cornell University (USA) between 1999 and 2001, he entered CNRS in France, at the Ecole des Mines de Paris. He became CNRS Research Director in 2013, and in 2014 joined the Materials Institute of the School of Engineering at EPFL, as an associate professor, and holder of the PX Group Chair, where he now heads the Laboratory of Thermomechanical Metallurgy.
Title: Multiscale approach for the control of metallic microstructures in forming conditions Authors: R.E. Logé, M. Bernacki Day/Room/Hour: Wednesday/ Room M500/ 08:30-09:10 Abstract: The modelling of metallic microstructure evolutions in forming conditions is traditionally treated by introducing homogenization (or mean field) schemes at each integration point of a finite element mesh. Typical limitations arise in trying to predict the formation of substructures, or new grain structures, in complex thermomechanical processes. It is shown that a strategic dialogue between mean field and full field models, including 2D or 3D geometrical descriptions of microstructures, can lead to progress in simulation capabilities, and improved understanding of the associated phenomena.
Speaker: Dr M. Megahed (ESI_Group, Germany) Dr. Mustafa Megahed obtained his Ph.D. from the Technical University of Aachen, Germany, in 1993. Since then he has been involved with commercial CFD offerings. He filled several positions in development, support and engineering service. He joined ESI Group in 2004 where he enlarged the European CFD business several fold. Dr. Megahed now manages the CFD & Multiphysics Center of Excellence, leading a team of researchers focused on the development of new algorithms and creation of new solutions. His team and he are involved in Additive Manufacturing modelling since 2008 investigating several net shape processes including Topology Optimization, Powder Bed
processes, Blown Powder and HiPping. Title: Modelling Additive Manufacturing Authors: N. N'Dri, H.-W. Mindt, O. Desmaison and M. Megahed Day/Room/Hour: Tuesday/ Room M500/ 08:30-09:10 Abstract: Additive manufacturing offers engineers design freedom utilizing the process ability to create new functional products. Harnessing this potential has proven extremely challenging due to large amount of process parameters that interact in a highly complicated way with the material and the product being produced. Physics based modelling might provide the required insight to understand and manage the interdependency of the build process and to provide a reliable predictive tool for product quality. Modelling advancements and validation examples will be presented.
Speaker: Dr Y. Urushiyama (Chief engineer of Honda R&D Co.ltd., JAPAN) Dr. Urushiyama is currently Chief Engineer at Honda R&D Co. Ltd in the field of Light weight vehicle and related topics. Since 2015 he is visiting Professor, in Innovative Composite Center of Kanazawa Institute of Technology. He obtained his PhD from Touhoku University in 2004. From 1983 to 1994, he worked in the field of noise and vibration stress at Honda Automobile R&D Center and from 2001 to 2010 in the field of light weight structures.
Title: Expectation and Issue of Using CFRP for Automobile Structure Author: Y. Urushiyama (Honda R&D Co.ltd., JAPAN) Day/Room/Hour: Monday/ Room M500/ 13:45-14:25 Abstract: Vehicle weight reduction is one of important issue in automobile industry. Expectation of CFRP technology which is one of?weight reduction technologies for automobile engineer are considered. But mechanical property of CFRP is affected according to the conditions under many fabrication processes. Using process simulation for composite is effective to grasp the various process influences in designing process of CFRP structures. In this presentation, I mention that the application of manufacturing simulations, such as for determination of tolerance is important.

Advances in finite element methods for the simulation of forming processes
We present some recent advances in finite element methods for the analysis of forming processes. These advances pertain to solid and shell finite elements for large strain solutions, contact analyses, improved explicit and implicit time integration schemes, the analysis of fluid-structure interactions, electromagnetic effects, and the development of "overlapping finite elements". The use of overlapping finite elements promises to be an avenue for very effective analysis schemes. Illustrative solutions are given to show the characteristics of the various methods discussed.

The so-called “Modulus Effect” is shown to be a universal phenomenon among
metals. This reversible but energy-dissipating mechanism produces
unexpected stress-strain curvature in the nominally elastic region, whereas
bond-stretching is linear. It affects springback and other small-strain
behavior significantly, but is seldom taken into account in such simulations.
The phenomenon is quantified for a diverse range of alloys. It is shown to depend to high degree of accuracy on
only material strength.

Cu/Al/Cu laminate rolling processes was carried out on a multifunction rolling mill. The thickness of Cu sheets was 300 μm. Four kinds of thicknesses of Al sheets were used: 16, 40, 70 and 130 μm. TEM images show that with reduction of the Al layer thickness, the fraction of porous after rolling increases. FEM was used to simulate the Cu/Al/Cu rolling processing. Calculated results reveal the size effect of Al layer thickness on their deformation characteristics.
Class A surface low prediction and correction has been a challenge in sheet metal forming applications. Based on ETA-Dynaform stoning simulation algorithm and full cycle simulation technology developed at FCA, the class A surface low correction is performed on multiple stamping applications. It is concluded that the newly developed method is the ice breaker for class A surface low correction in auto industry.
Creep-age-forming of a thick Al-Cu-Li sheet is studied. An industrial stamping press is used to form a double curvature panel at a reduced scale. This forming, which includes several relaxation steps, is modelled using ABAQUS. A material model describing an elasto-viscoplastic behaviour with anisotropy effect has been identified and implemented in ABAQUS using Fortran subroutine. The numerical model is validated by comparing experiments and numerical results in terms of deformed shapes and an improved forming cycle is suggested.
Press hardened steels like 22MnB5 have high mechanical strength making it possible to achieve weight savings for automotive applications. With these steels, the high thermo-mechanical stresses in blanking operations may damage blade tools. To get better insight into the damage mechanisms, a finite element model is developed to reproduce the thermo-mechanical loadings. The effect of blank’s initial temperature, cutting clearance and thermo-mechanical behaviour of tools are investigated. Experimental hot blanking tests are performed in order to examine simulation relevance.

This paper presents the experimental and numerical results of the effect process parameters on ovality in cross wedge rolling (CWR) for hollow engine valve without mandrel. The experiments and numerical analyses suggest that the following parameters represent the best conditions for CWR of hollow engine valve: 30°-34° for the forming angle(α), 5°-7° for the stretching angle(β), 0.2-0.3mm for the mold void width(L) , and 65%-70% for the area reduction(Ψ).
Creating a finite element analysis model that can accurately model wrinkling is challenging. Therefore creating a model that can introduce imperfections that are comparable to reality can improve the resolution and predictability of the defect. This can be achieved by characterising material properties, implementing effective parameter studies which will eventually produce novel manufacturing techniques to reduce the chance of defects occurring.
Ingot forging processes often consist of several successive deformation steps with high interpass times, during which metadynamic recrystallization (MDRX) occurs. Two-stage isothermal compression tests were carried out at 1150C and 1200C with strain rates of 0.25-2s-1 and interpass times of 5-25s. Based on the experimental results, a material model for MDRX is proposed. The constitutive model was implemented in ForgeNxT1.0® software to simulate the multistage compression. Results from the material model are consistent with the numerical analysis and experimental results.
Order of Punch diameter, sheet thickness, clearance and die wear on punching-process are about 10mm, 1mm, 100μm, and 10μm. So, detailed punching-process analysis is difficult. Furthermore, the analysis that in consideration of die wear is not conducted almost. Therefore, we set mesh size at neighborhood of die edge and punch to 1/10μm. And, we do the analysis in consideration of die wear. From this analysis, we investigated stress, incremental strain and equivalent strain on different types of die wear status.

Cold Workability limits strength enhancement of austenitic materials through cold deformation. The intrinsic workability is the material characteristic whereas state-of-stress workability is governed by nature of applied stress, strain rate and geometry of deformation zone. For Cold Open Die Forging (CODF), multipass workability is essential. In this work, FEM tool FORGE-3 is used to optimize CODF on hydraulic press by analysis of stress-strain profiles and use of Latham-Cockroft damage criterion. Study recommends optimized process parameters, die combinations and pass-schedules
Usibor®1500 has very high mechanical strength making it possible to achieve weight savings for automotive applications but needs to be hot formed. To increase productivity, a new process based on Joule effect is developed to heat blanks before hot stamping. Numerical simulation is used to optimize the heating of complex shape blanks. A thermoelectric model using COMSOL Multiphysics® with MATLAB is developed to achieve a homogeneous thermal field. Special care is taken to the contact resistances between electrodes and blanks.
The numerical analysis of plasticity in metal forging and sheet metal forming has been advanced by the many contributions of J.-L. Chenot and co-workers in recent years. Here we present elements of a new plasticity theory for atomically thin, 2D materials such as graphene and hexagonal boron nitride, in which dislocations exist as point defects. We present numerical results showing dislocation nucleation and motion under applied loads, and make comparisons with plastic deformation mechanisms in 3D materials.
This work aims to propose a 3D numerical methodology to predict the fatigue life of mechanical components. Specific coupling functions between fatigue damage and elastoplastic constitutive equations are proposed. Both the theoretical and the numerical aspects are presented and attention is paid to the specific algorithm to calculate the fatigue life under cyclic loading paths. The proposed numerical methodology is tested for the computation on the fatigue life of a 316L steel cylindrical specimen
The plastic deformation of two rolled magnesium sheets under tensile and compressive loading conditions is studied. A phenomenological plasticity model in which the primary deformation mechanisms, slip and (extension) twinning, are treated separately is developed and incorporated in the finite element framework. Deformations caused by these mechanisms are modelled by a symmetric and an asymmetric plastic potential. It is demonstrated that the model predicts the deformation mechanisms during shear loading as well as the macroscopic response of the sheets investigated.

In this paper the numerical analysis of bevel gear forming is presented. Simulations are made by means of FEM using Deform 3D software. Disributions of stress, strain, temperature and Cockroft - Latham damage criterion are presented at various process parameters. Obtained shape of final part and calculated loads during the process course can be usefull for the further practical applications.
An intelligent regression technique is applied for sheet metal bending processes to improve bending performance. This study is a part of another extensive study, automated sheet bending assistance for press brakes. Data related to material properties of sheet metal is collected in an online manner and fed to an intelligent system for determining the most accurate punch displacement without any offline iteration or calibration. The overall system aims to reduce the production time while increasing the performance of press brakes
A new simulation framework of Double-Side Incremental Forming (DSIF) is proposed to capture the influence of the machine compliance. The tool shafts were modeled as elastic bodies, and in order to speed up the simulation via mass scaling, both local damping and velocity boundary conditions were imposed. The results of simulations showed that the tool gap was unexpectedly enlarged because of machine compliance which affected the tool contact with the sheet, thickness distribution, and geometric accuracy in DSIF.
The flat-wedge cross-wedge rolling (CWR) deformation and interfacial slip of GH4169 superalloy were investigated experimentally and numerically using a coupled thermo-mechanical finite element analysis (FEA) model. The simulation and experimental flat-wedge CWR forces showed well agreements except near the end of the stretching zone. The simulation analysis showed that the temperature distribution in the work piece was non-uniform during the flat-wedge CWR. The experimentally measured tool-workpiece interfacial slip was in good agreement with that predicted by the FEA model
The mechanical anisotropy of hot-rolled Mg alloy AZ31 is investigated both experimentally and numerically. First, five different specimen orientations with tilt angles between the normal direction and longitudinal specimen axis are used to experimentally study the mechanical anisotropy under uniaxial tension. Then, the Elastic Visco-Plastic Self-Consistent (EVPSC) model is applied to simulate the uniaxial tension tests. It is demonstrated that the EVPSC model is able to reproduce the anisotropic behavior observed in rolled AZ31 plate under uniaxial tension.

Improving the formability of the material is an important issue in the deep drawing process. Heating the material above its recrystallization temperature drastically increases formability but it results in the loss of its mechanical properties. To improve the drawing ratio, only the heating of the flange region in the warm range is studied on DP600 sheet steel by numerical simulation. Thermo-elastic-plastic FEM analysis of deep drawing at several drawing ratios is performed and compared with experimental results.
A framework for a combined anisotropic-kinematic hardening model of large-strain cyclic plasticity is presented, and the details of modeling which is based on the Yoshida–Uemori model are described. The shape of the yield surface and that of the bounding surface are assumed in the model to change simultaneously. The model was validated by comparing the calculated results of stress–strain responses with experimental data of an aluminum sheet and cyclic straining in three sheet directions on an advanced high-strength steel sheet.
The numerical simulation of forming processes involving titanium is challenging. Besides anisotropy, it exhibits strong tension compression asymmetry and, given the direction dependent twinning of the hexagonal lattice, substantial anisotropic hardening. The present work proposes an extension to the CPB06 yield function, in order to capture the evolution of the yield surface shape in dependence of twinning induced plastic deformation. A non-associated flow rule is introduced to correct the flow direction. The model is validated with a cup drawing test.

The sudden growth of additive manufacturing is generating a wave of innovation in traditional manufacturing technologies. In this paper, we propose a rapid tooling compensation method based on the explicit FEM simulation coupled to a geometrical optimization algorithm for designing the stamping tools. The compensation algorithm has been improved by considering the deviations between the stamped and designed components. The FEM model validation has been performed by comparing the results of a DOE done at different values of press force.
FE-CA model is built to simulate the microstructure of DP600 steel during solidification. A moving conical heat source is applied to achieve temperature field during laser welding. The linear interpolation method is used to transfer node temperature of Abaqus to cell temperature of CA. With the consideration of temperature and solute concentration, the solidification is simulated. The model gives equiaxe and column dendrite grain growth. Competitive growth between different dendrite arms is presented. Simulation result shows good agreement with experimental.
Combining different materials for producing high performance parts opens a broad range of high functionality and applicability. Scope of this project is the investigation of a new method to process metal and plastic within one single production step using impact extrusion. In this study, first FEM results of the combined impact extrusion of metal and plastic will be presented. The aim of the numerical investigation is to achieve a plastic flow of the polymer material during the metal forming process.
High strain rate deformation in an electromagnetic pulse technology could play an important role in metal forming and joining processes. Based on this technology, ring expansion test has a good potential for the material characterization at high strain rate. In this work, coupled 3D mechanical-electromagnetic simulations were performed to investigate the suitability of this technique to characterize material parameters. Preliminary results show the development of biaxial stresses while the proposed shilling mechanism eliminates the axial stress component on the rings.

The concept of shape-manifold is applied here on the optimization of a deep drawn blank considering parametrized tool geometries. By adopting this concept, the closed realistic post-springback shape of the blank to a given ideal target shape is obtained. The global approach is fully automated, from the generation of the tool geometries, to the identification of the optimized design parameters. This approach was successfully applied either on simple 2D and complex 3D industrial test cases.
The presence of voids after casting processes of large metal workpieces require the use of adapted hot metal forming processes to deliver sound products. Yet, there is at present a lack of knowledge regarding void closure mechanisms and there is no reliable model that can accurately predict void closure. A new model accounting for both stress triaxiality ratio and Lode angle is proposed. Based on an advanced multiscale approach, this model also accounts for voids shape and orientation.
Pharmaceutical high barrier blister packages are manufactured from aluminium-polymer laminate foils (e.g. consisting of PA-Al-PVC layers). By a cold stretch forming process cavities are formed. The aim of this work is to determine a homogenized elastic-plastic description of the laminate by micromechanics. Therefore, the unit cell technique is used where the layers are mapped in a representative volume element. The obtained homogenized material model is applied to simulate the stretch forming to gain more insight into the forming process.
Electrohydraulic forming (EHF) process is one of the high-speed forming process which uses the high voltage discharge in water. Shock wave resulted from the discharge is propagated to the blank and it makes the blank deformed. In this study, a finite element model of EHF process was developed using Arbitrary Lagrange-Eulerian (ALE) Multi Material formulation in LS-DYNA. The results show that the numerical model for EHF was successfully made and that bouncing effect didn’t affect the formability of the blank.

Instrumented indentation test has been used to determine material parameters with two different sources of information. Based on the recent shape-manifold identification approach, we formally demonstrate, in the scope of manifold, the non-uniqueness of the solution to the inverse problem based on load-displacement curves. The identifiability is also compared for P-h curve and imprint mapping, highlighting the manifold's ability to estimate the maximum number of independent material parameters that may be determined with a given experimental setup.
A new full field numerical approach for the simulation of dynamic and post-dynamic recrystallization will be detailed. A level set framework is employed to link the crystal plasticity finite element method with the modeling of recrystallization. Plasticity is calculated through the activation of slip systems and provides predictions for both SSDs and GNDs densities. These predictions control the activation and kinetics of recrystallization. All developments are validated for 304L stainless steel and implemented in the Digi-mu software for industrial purpose.
A finite-element simulation of the blanking process is used to predict the process forces and the geometry of the cutting surface. A fully-coupled elasto-plastic-damage model considers the influence of shear and compression-dominated stress states on the propagation of damage. This approach is advantageous for the analysis of different blanking processes and enables the prediction of the core compression, which provides valuable information for the development of analytical models.
In metal forming process, application of electric pulses changes the material property owing to electroplastic effect. With this effect, the electromagnetic forming (EMF) process can be a more efficient metal forming process. In this study, EMF process on Al5052 alloy under intense electric current pulse was numerically simulated by finite element method. The numerical simulation results are compared with experimental results. It is shown that the electroplastic effect can successfully reduce the strength and the EMF force.

It is well known, that under conditions like hamming or in cases of deep drawing with small radii fracture limits arise, which do not correspond to the classical FLC. In the talk a generalized FLC-R concept will be presented, which includes the influence of strain gradients induced by bending into the consideration. The corresponding limits will be experimentally evaluated identifying the rupture strains on the “classical” Nakajima specimens.The new theoretical approach will be applied to special Al-multilayer sheet materials.
Aleatory uncertainties in material properties, blank thickness and friction condition are inherent and irreducible variabilities in sheet metal forming. Optimal design configurations, which are obtained by conventional design optimization methods, are not always able to meet the desired targets due to the effect of uncertainties. This paper proposes a multi-objective robust design optimization applied in order to tackle this problem. Results obtained on a U shape draw begin benchmark show that springback effect can be control by optimizing process parameters.
IN718 alloy is an important material used for aero-engine turbine disk. The microstructure of the alloy is sensitive to the hot deformation parameters. Generally, the sizes of turbine discs are large, and the shapes are complex. Therefore, the defects of coarse grain and duplex grain often appear in the forgings. In this paper, the evolution of microstructure during the cogging, upsetting and hot die forging in the manufacture of IN718 turbine disc were predicted.
Multi-material domains are often found in industrial applications. Modelling them can be computationally very expensive due to meshing requirements. The finite element properties comprising different materials are hardly accurate. In this work, a new homogenization method that simplifies the computation of the homogenized Young modulus, Poisson ratio and thermal expansion coefficient is proposed, and applied to composite-like material on a printed circuit board. The results show a good properties correspondence between the homogenized domain and the real geometry simulation
Oxides Dispersed strengthened (ODS) stainless steels are foreseen for fuel cladding tubes in the coming generation of fission sodium cooled nuclear reactors. Classically those steels are cold formed as cladding tubes by a sequence of milling passes with intermediate heat treatments. This study focuses on numerical simulation of tube cold pilgering by High Precision Tube Rolling (HPTR). A 3D Finite Element Method mechanical analysis of the HPTR process is proposed. Results are confronted to experiments regarding geometry and residual stress.

This paper presents the results of a numerical analysis of the helical rolling process for producing 25 mm diameter workholding bolt using multi-wedge helical tools. The numerical modelling was performed by FEM using the commercial Simufact Forming v. 12 simulation software. The modelling was performed in a three-dimensional state of strain and included a full thermal analysis. As a result, the changes in workpiece shape as well as the distributions of strains, temperature, damage, loads and torque were determined.
A number of parts involved in the automotive industry are made of bent thin sheets. Unfortunately, classical predictions based on Forming Limit Diagrams are not applicable in case of heterogeneous strain distribution over the thickness of the metal sheet. This limitation generally leads to underestimating the formability limits. The aim of the present contribution is to propose an extended Marciniak‒Kuczynski approach that is able to take into account the effects of bending on formability.
In this work the manufacturing of patient-oriented titanium prostheses using innovative processes, like superplastic forming (SPF) and single point incremental forming (SPIF) has been investigated. Numerical simulations were carried out to: (i) define the process parameters for the SPF implementing suitable material constants evaluated through a preliminary material characterization; (ii) evaluate the temperature distribution in the SPIF due to the adoption of high speed. Finally, numerical results were experimentally validated and the reliability of numerical models checked.

Multicomponent process for production of high performance gearwheels combines both high power density and high lightweight potential. Whitin this paper, the focus is on manufacturing of an assembled gearwheel using cold forging and simultaneously joining of the gearwheel body and a gear ring. In this study, FEA results regarding the joining of two different materials for assembled gearwheels will be presented. The aim of the numerical investigation is to achieve a robust forging process and define appropriate tool parameters.
In this paper, the micro-formability of thin sheets is investigated by a numerical approach. A coupled elastic-plastic-damage model is used to predict forming limit diagram according to the micro-Marciniak tests. The identification of the ductile damage model is first performed from micro-single point incremental forming tests using inverse finite element method. Finally, both the micro-forming limit curve and the micro-forming limit stress curve are plotted.
The newly proposed incremental roll forming process for the manufacture of 3D structural pipes employs several pairs of roll assemblies in the rolling direction. All the rolls can be positioned in any direction, so that it is possible to form various shapes of the structural pipe members through twisting, two or three dimensional bending, and cross-section forming. In this paper, the key process parameters are designed for improvement of the product quality by using FE simulations.

The 3D finite element simulations of long product rolling can be significantly sped-up by focusing only on the steady state. A staggered fixed-point algorithm has been introduced to compute alternatively the mechanical fields on a prescribed domain and the geometry correction. This paper focuses on the resolution of the geometry correction for unstructured 3D meshes, parallel computing, and complex shapes with strong contact constraints. Accuracy, robustness and efficiency are compared to conventional incremental formulations on actual metal forming problems.
The hydroforming of extruded and fully-annealed 6061 aluminum tubes is studied using a combination of experiments and analysis. The experiments were performed in a custom tube-hydroforming facility using extruded Al-6061-O tubes of 60 mm outside diameter and 3 mm thickness. The tubes failed by bursting. The experiments were simulated in Abaqus/Standard using solid elements. The von Mises model failed to capture burst, so that the isotropic Hosford 1972 and anisotropic Barlat et al. Yld2004-3D non-quadratic yield functions are considered next.
In the recent decades the finite element method has become an essential tool for the cost-efficient virtual process design in the metal forming sector in order to counter the constantly increasing quality standards as well as intensified international competition. The main objective of this work is a modelling algorithm, which allows predicting die wear with respect to a geometry update during the forming simulation. Changes in the contact area caused by geometry update lead to the different die wear distribution.
The finite element simulation is currently a powerful tool to optimize forming processes in order to produce defect-free products. Wrinkling and springback are the major geometrical defects in sheet metal forming. The prediction of such defects requires accurate numerical models, namely the mechanical behavior of the sheet and the frictional contact conditions between the sheet and the tools. This study presents the experimental and numerical analysis of geometrical defects arising in the sheet metal forming of a warping geometry.
This paper deals with 3-D composite impact numerical analysis process by using LS-DYNA and its experiment. And its experiment is conducted by using electromagnetic launcher which is propelled by electromagnetic force and has space advantage than air pressure force. The impact moment is recorded by high speed camera which is FASTCAM SA-X2. And confirm the impact resistance properties by calculating absorbed projectile’s kinetic energy, blank’s deformation strain energy and shape from both approaches. The impact velocity range is ~500m/s.

Different routes to produce a product in a bulk forming process can be described by a limited set of process parameters. The parameters determine the final geometry as well as the distribution of state variables. Ring rolling has been simulated using different parameter settings. The final state variable fields have been subjected to Principal Component Analysis. Interpolation of principal component amplitudes in process parameter space gives an excellent representation of the fields and is useful as metamodel of the process.
Two advanced models for stress transients after strain-path changes have recently been proposed for cases of steel and aluminum, respectively. The current work is a comparison of predicted material behaviors based on these two models. It is concluded that both models can be extended to cover each other’s materials. However, there are still various limitations related to each model, such as permanent orthogonal softening, transient r-value evolution and correct predictions of more complex double strain-path changes.
Asymmetric sheet rolling is a method of severe plastic deformation (SPD) for production of aluminium alloys with UFG structure. Prediction of sheet temperature during SPD is important. The temperature of sheet is changed due to the conversion of mechanical work into heat through sliding on contact surfaces and high shear strain. Paper presents the results of FEM simulation of the effect of contact friction, rolling speed and rolls speed ratio on the heating of aluminium sheets during asymmetric rolling.
In order to form the thin-walled hollow parts with large deformation, a technology has been developed in present study by combination of hydroforming with moving dies similar to forging process, known as a hydroforging technology. Based on the finite elements simulation, the process of hydroforging was investigated to avoid thinning, wrinkling, and bursting due to unreasonable selection of the internal pressure. The suitable loading path was discussed. The results from simulation keep a reasonable agreement with that from experiment.
A new method that can improve the precision in predicting plate deformation during the plate forming by line heating is presented. A Finite Element Analysis has been performed. The proposed method consider the influence of multiple heating lines: overlapped, parallel and crossed heating lines. It was found that the inherent deformation produced by multiple heating lines applied close to each other is influenced by residual stresses produced by previous heating lines. New relationship are proposed to consider such influences.

Closed-die forging and ram bending of a sling shackle was simulated in 3D using Abaqus software. The predictions were validated against experimental data obtained over 80 shackles. Influence of lubrication, workpiece temperature, flow stress model and tools kinematics was investigated. Evidence of underfiling due to low temperature has been demonstrated numerically. Results showed that transportation time from the furnace to the press and the workpiece manipulator itself play an important role in the proper manufacturing process of sling shackles.
The constitutive response of a rare-earth magnesium alloy rolled sheet (ZEK100) is evaluated at room temperature under quasi-static conditions for a range of stress states including shear, uniaxial tension, uniaxial compression, plane-strain, and equal-biaxial tension. The anisotropy, tension-compression asymmetry, and distortional hardening of ZEK100 are described, highlighting the need for suitable modelling approaches. Using the experimental results, the CPB06 yield function is calibrated at different plastic work levels to investigate the evolution of shape of the yield locus with deformation.
The technology of high-ratio differential speed rolling (HRDSR) with high contact friction can be used for production of aluminium alloys with UFG structure. But a high friction coefficient is not desirable because of the increasing of the material damage. The paper presents a numerical analysis of the rolls wear and material damage during HRDSR of aluminium alloy 7075. The FEM was used to calculate the rolls wear by Archard’s model and material damage by normalized Cockroft-Latham model.
Transformation induced plasticity (TRIP) steels undergo a phase transformation from an austenite phase to a martensitic phase that enhances the ductility and strength. A phenomenological formulation for TRIP 800 steel is employed to study the thermo-mechanical behaviour during large strains. The model is calibrated for a wide range of strain rates, temperatures and strain paths and used in Marciniak-Kuczynski (M-K) based forming limit diagram (FLD) predictions. The results show the interaction effect of strain-rate, temperature and martensite evolution on formability.

The phase-field method has emerged as the method of choice for simulation of microstructure evolution and phase-
transformations. It has wide applications in solidification and solid state transformations in general. Recently the method
has been generalized to treat large deformation and damage in solids. A full-field simulation will be presented starting from solidification, homogenization, heat treatment and forming,
and ending with the evolution of damage during large deformation. Aspects of numerical discretization, efficient numerical integration and massive parallelization will be
discussed.

The presentation will highlight some key developments in industrial forming simulations in the early days (eighties and nineties) with the focus on bulk forming and algorithm development at the University of Twente (Huétink) and at CEMEF (Chenot). Subsequently, the application in process optimization will be discussed, with contributions from the same groups. An outlook for the integration of process models in ‘model based control’ of forming processes will be given, for which reduced order models are essential.
A cohesive zone element formulation is developed for the bonding and debonding based on a traction-separation law, where the focus is on the bonding and joining process due to plastic interface deformations. The process of roll bonding. Regarding the strength of the interface bonding, a model correlating the interface bonding strength and interface stretch during roll bonding is proposed. It is shown that the deeper the sheets get rolled, larger forces are necessary to peel them afterwards.
This paper presents a new method for deep drawing process control, characterized by: i) segmented-multiple moving drawbeads; ii) optimal reference trajectory for drawbeads position; iii) in-process control where controlled variable is the amplitude of deviation of the actual instant workpiece surface geometry with respect to the surface geometry; iv) periodical validation, calibration and updatation of the control model and reference trajectory; v) reduced order modelisation of the complex deep-drawing process. Experimental results confirms the validity of the new proposed method.
The hot deformation behavior of 05Cr17Ni4Cu4Nb alloy was investigated at the temperatures from 1000 to 1200℃ and strain rates from 0.01 to 10s-1 on Gleeble-1500 thermo-simulation machine. And then, a new constitutive equation incorporating the effect of the strain on the deformation behavior was proposed based on the Arrhenius-type equation. Finally, the developed constitutive equation was applied to the hot forging process of turbine blade.

Polymer processing involves three thermo-mechanical stages: Plastication of a solid to an homogeneous fluid which is shaped under pressure in moulds or dies and finally cooled and eventually drawn. Physical properties of polymers make modelling a complex challenge. Several examples of extrusion, film processing and injection moulding will be presented
Recently, an original full field model using the level set
method in a finite element framework has been introduced and validated at the Mines ParisTech - Center for Materials
Forming. This approach has demonstrated its potential for the simulation of 2D or 3D large scale grain growth and
recrystallization problems. Through the development of the Digi-µ software by Transvalor, this methodology is now
considered for industrial applications.
The Piwnik and Plata pressure-time bonding criterion was applied to Friction Stir Welding, Linear Friction Welding, Porthole Extrusion and Roll Bonding. A neural network was set up, trained and used to predict the bonding occurrence starting from the main field variable distributions calculated through specific numerical models developed for each process. The analysis of the results permitted to predict the occurrence of solid bonding and to highlight differences and analogies between the processes in order to obtain sound solid welds.
Over thinning of wall thickness occurs easily during multi-pass deep drawing spinning. The influence of surface-profile and movement-path of roller on thickness thinning was studied based on numerical simulation and experimental research. The results show that for 1060-O Aluminum blank with 1.8mm thickness, the thickness thinning ratio reaches the minimum by using the roller of R25-12 and reduces significantly when spinning from the middle of the blank. The experiment results conform well to the simulation one.
In the aerospace industry, there is a great need for new materials which exhibit improved mechanical properties, increased tensile strength, hardness, and toughness at a reduced weight. A brief introduction of severe plastic deformation (SPD) is presented along with different processing techniques for producing nano-structured materials through SPD. Finite element modeling and simulation of Equal Channel Angular Processing (ECAP), High Pressure Torsion (HPT), Twist Extrusion (TE) and Repetitive Corrugation and Straightening (RCS) is attempted and the results are discussed.

Titanium prostheses are artificial components used during cranioplasty, which require an adequate anchorage system. Because there are no specific guidelines regarding this system, aim of this study was to develop a decision support tool for the identification of the optimal parameters, in terms of screw geometry and overlap dimension considering different damage areas and possible but unforeseen loads. This tool could be considered very helpful for surgeons to realize a rapid and precise anchoring between prosthesis and skull bone.
This paper shows a 3D finite element model for flexibly rolling of a 250 μm thick workpiece with reduction of 20 to 50%, and rolling phase with thinner thickness indicates a better ability to decrease the surface roughness. Four types of initial workpiece surface roughness are studied in the simulation, and the influences of process parameters, such as friction coefficient, rolling speed and roll gap adjusting speed, on surface asperity flattening of workpieces have been numerically investigated and analysed.
The aim of this paper is to analyze the influence of the main factors that introduce errors in springback analysis of the single point incremental forming process: the material properties (especially Young modulus) and the constrained nodes scheme. The Ls-dyna software was used for numerical simulation. The experimental research was conducted on a robot and an Aramis measuring optical system allow the real-time determination of strains, thickness reduction and springback at the end of the forming process.

By means of Optimal Latin Hypercube experimental design, a design matrix with 17 factors and 50 levels is generated. Based on the design results, quadratic response surface models are established to describe the relationship between design variables and evaluation objectives. Then the layout of the conformal cooling channels is optimized according to a multi-objective optimization method to find the Pareto optimal frontier which consists of some optimal combinations of design variables that can lead to an acceptable cooling performance.
The present study is focused on the first steps of recrystallization and texture characterization in an IF-Ti steel 35% deformed by uniaxial tension. Global texture of the deformed state shows the development of a partial a fiber with reinforcements close to the {111} <110> and the {001} <110> components. After complete recrystallization, retention of the deformation texture is observed. A multi scale study is proposed for explain the changement of recrystallization.
In this work, a new advanced simulation method for welding processes based on the Vademecum-Generalized Finite Element Method (V-GFEM) and other Model Order Reduction techniques is proposed. This approach improves the performance of current methods, computing “off-line” parametric prior information (using Computational Vademecums) which enriches the approximation space. This allows us to greatly diminish the use of costly “on-line” adaptive techniques, such us adaptive mesh refinement. We demonstrate its performance for both the thermal and mechanical analysis of welding.
Based on some experimentation in NUM3D Platform, we integrate the possibilities of additive manufacturing processes and the characteristics of the materials. We extend to the specific property inherent in form and control to define a new tetraptic CPMF (Control/Process/Material/Form). We propose, from this tetraptic, an Oriented Object Modelization suited to Additive Manufacturing. In this paper, we set up a virtual representation specific to industrial manufacturing. In fine, this representation is intented to be used in a decision-support tool.
The kinetics of the crosslinking reaction of silicone rubbers was investigated by current techniques: differential scanning calorimeter and oscillating disk rheometry. From the kinetic experimental data, different kinetic analysis methods were used to determine the activation energy of silicone, such the Kissinger-Akahira-Sunose and the integral methods. The results show the influence of the chemical composition of silicone, the modeling used and the applied kinetic methods on the activation energy and the evolution of activation energy during the crosslinking reaction.

This paper discusses a new parameter identification scheme for complex yield criteria of sheet metals using experimentally determined load and strain distributions and combining analytical stress analysis on sectional strain data with common inverse analysis. The approach is suitable for specimen with a non-homogenous strain distribution over specimen’s section and reduces computing time compared to common methods like iteratively updated FEM considerably. It serves to identify a set of parameters in a fast and precise manner, describing the material behaviour.
A polycrystalline model is used to describe the anisotropic mechanical behaviour of an AISI 316L austenitic stainless steel. An experimental database has been established (tension and shear tests) and used to identify the stress-strain response of the material. The results are then compared with macroscopic models using Hosford’s yield surface. Both models are used to simulate a sheet metal forming process using a finite element code.
P.O.D. and D.E.P.O.D. model reduction methods are applied to semi-thick sheet forming process of the bulge test. The problem is characterized by large deformations, instability development, implicit velocity / pressure formulation and unstructured meshes of tetrahedrons. P.O.D. allows reducing significantly the number of unknowns to around ten unknowns while keeping the results accuracy and preserving instability manifestation. The resulting metamodel remains accurate for different materials, thicknesses and pressure cycles. The D.E.P.O.D. approach allows extending further its validity domain.
Numerical simulations of the 3D printing of CNT-reinforced thermoplastics using an SPH method accounting for the description of fibre orientation are presented. Classical microstructural fibre suspension models are implemented within the SPH framework and the fluid is described as a generalised Newtonian fluid. The deposition of a material layer in the vicinity of the nozzle is simulated and results for the impact of fibre aspect ratio and volume fraction on the fibre orientation state within the deposited layer are reported.
The extensive use of composite materials in automotive structural components with high mechanical requirements is today limited by production rates amongst others. The compressive resin transfer molding process could overcome this limitation enabling car manufacturers to reduce the cycle time of composite parts production. This paper will present new modelling techniques used to simulate the complex 3-dimensionnal resin flow occurring during compressive RTM process: inter-penetrant meshes and Fluid/Solid coupling.

New forming machines are typically incremental improvements on existing designs. Tedious simulations and testing are required for insights on those possible improvements. A method for inventing features of flexible sheet forming processes is explored. An inverse problem is solved by starting with a desired geometry and "un-forming" the part. A selection of kinematic constraints is applied while minimizing the plastic work on the workpiece. The resulting deformation reveals required forces on the part and informs machine design.
Commercial purity titanium has a hexagonal close-packed structure and exhibits unusual anisotropy and asymmetry at room temperature. In order to examine the mechanical behavior of commercial purity titanium, in-situ tensile tests are performed under an orientation imaging microscope. The observed microscale behavior is analyzed and used for developing the crystal plasticity finite element model of commercial purity titanium. Based on the microscale analysis, an anisotropic constitutive model is proposed for macroscale finite element simulation.
In this work we present a new data compression model aimed to reduce the huge amount of data generated while simulating laser assisted manufacturing processes with multiphysical models developed using OpenFOAM® simulation software. The overall compression efficiency of such model is compared versus GNU-Zip®, -the currently offered alternative in the software package- and other commercial tools for our cases of interest as well as for a standard tutorial case.
A three dimensional model for material deposition in Selective Laser Melting (SLM) with application to alumina-zirconia eutectic system is presented. A Beer-Lambert heat source model taking into account the material absorption is derived. The Level Set method with multiphase homogenization is used to track the form of deposed layer and the thermodynamic is coupled to calculate the melting-solidification path. The influence of different process parameters on melt pool profiles and bead shapes is discussed.
This paper shows a method to determine rheological parameters of rheological constitutive models for powder injection moulding. A thermophysical characterization on the powder and feedstock was carried out. The data collected were used for the model’s parameter identification. The used material that is nickel-chromium-based superalloy is typically used in high-temperature and high-performance applications, particularly in the aeronautic industry. However, this nickel alloy is rather expensive; it is why it is very important to reduce the amount of generated wasted material.

A new viscoplastic formulation for “Pseudo Inverse Approach” (PIA) is proposed for modelling forging process. This method is coupled with an optimization procedure to obtain the optimal part tool shape for a metal forging process. The equivalent plastic strain variation in the final part and the maximal punch force during the forming process are taken as multi-objective functions. The tool shapes are represented by B-Spline curves. The vertical positions of the control points of B-Spline are taken as design variables.
In this paper, localized necking in metal/elastomer bilayers is investigated using both the bifurcation and the initial geometric imperfection approaches as localization criteria. The rate-independent crystal plasticity theory coupled with both the Taylor and the self-consistent scale-transition schemes is used to describe the behavior of the metal layer. As to the elastomer substrate, a neo-hookean law is used. A comparative analysis of the predictions yielded by the above-mentioned localized necking criteria and constitutive theories is conducted.
A family of linear and quadratic solid‒shell (SHB) elements is presented to model 3D thin structures. Based on reduced integration and special numerical treatments, SHB solid‒shell elements are capable of simulating most thin structural problems with an accurate description of the various through-thickness phenomena. In this paper, the performance of the SHB elements, combined with advanced anisotropic elastic and plastic behavior models, is assessed through various quasi-static and dynamic benchmark problems as well as complex sheet metal forming processes.
The paper describes the numerical model developed to predict the thermo-mechanical behavior during welding process. FEM combined with an efficient mesh refinement technique accurately predicts the Heat Affected Zone and therefore mechanical distortions or residual constraints in the assembly. Thanks to a level-set method, the weld’s shape is no longer considered as an input but becomes a result. Likewise, potential air gap between assembled parts is considered. Recent applications are reviewed and future developments are discussed.
The article deals with the effect of the normal stresses on the predicted flow front and pressure distribution during the filling stage of the thermoplastic injection molding. The normal stresses are predicted using the non-linear Criminale-Ericksen-Filbey model incorporated into a comprehensive 3D simulation software for moldfilling analysis. The additional term improves the prediction of the so called ear-flow effect (melt racing on the edges of the cavity).

The Expansion process is one of the critical point in the manufacturing chain of stainless Steel seamless pipes for Oil&Gas Industry. This work describes an optimization of the Expansion process based on sensitivity analysis for different process parameters for Alloy28 using FEM. The optimization is focused on reduction of tool wear, defects and material waste. The demand from this sector to obtain new grades with specific properties and the high cost of experimental trials justifies the use of simulation tools.
A "micromorphic", second-gradient model applicable to ductile porous materials has been proposed, as an improvement from the fundamental work of Gurson that take into account the physical mechanisms responsible for ductile damage. The model has been applied to the study of fracture of the decarburized layer of a Dissimilar Metal Weld. The model successfully reproduces the crack path experimentally observed in a notched tensile sample extracted from this weld, different from the one predicted by the first gradient model.
In this method, the required force (load) is reduced to the greatest possible degree through elimination of flash channel; however, this would also decrease the positive effect of flash channel, namely filling the gaps and pores within the mold. Cross die forging procedure provides a way for providing a better preform design which ensures that the mold is filled without allowing the material to enter the flash channel.Examples of such parts are valve’s body, T-junctions, etc.
The objective of this work is to show the ability of the finite element P1/P1 to simulate a welding operation. First of all, while the P1/P1 finite element is known to be not LBB-stable, we study the properties of this element and the conditions of its correct use. Then we propose a new simple and robust stabilized formulation that prevents parasites pressure modes. Finally, we develop a simulation example of a circular MAG welding operation.
The crystal plasticity model is extended in the finite element method and thermal behavior is integrated in the constitutive equations. Moreover, damage evolution is reflected in the simulation using continuum damage mechanics model. Void evolution and thermal effect could both be shown in the simulation.Thermal parameters are determined in a fitting test of representative volume element to compare with the experimental data. The results prove that the mechanical tensile behavior of aluminum alloy could be well described at different temperatures.

Correlations may affect the output of composite significantly. To address these correlations, a novel approach for uncertainty analysis based on copula function assisted by reanalysis method is suggested. The Copula function is utilized to address the correlations of input variables.To save the computational cost, an efficient fast computation method, reanalysis method is integrated in the frame. The numerical test demonstrates that the proposed approach is an efficient uncertainty analysis tool for the practical engineering problems.
In this paper, nonlocal anisothermal elasto-visco-plastic constitutive equations strongly coupled with ductile isotropic damage are developed to simulate sheet metal forming processes under large anisotropic plastic strain. New micromorphic temperature and damage variable are introduced into the principle of virtual power and additional balance equations are obtained. Thermodynamically-consistent nonlocal constitutive equations are deduced. This model is used to simulate various sheet metal forming processes at high temperature. Some applications are performed to show the predictive capabilities of the proposed methodology.
There are only few applications of semisolid processing of higher melting point alloys. Steel is a particularly challenging material to semi-solid process because of about 1400°C temperatures involved... An experimental protocol was determined to characterize the thermomechanical behaviors. Uniaxial tensile and compressive tests were carried out on semi-solid specimen having >0.8 solid fraction for different ram speeds and temperatures. Experimental results are used to improve the thermomechanical modelling of steels behaviors at semi-solid state.
Thermal 2D and 3D FE models were developed to retrieve the high temperature gradients created during multi-layer laser cladding deposition of high speed steel powder. The model can deliver the complete thermal history of the deposition process and was validated by experimental measurements. The flux input in the 2D and 3D models are identified using theoretical formulae based on laser power. The thermal history of the specimens is of great importance to predict cracking (thermo-mechanical model) and microstructure (thermo-metallurgical model).
Fragmentation of α lamellaes and subsequent spheroidization of α lathes in α/β titanium alloys occuring during and after deformation are well known phenomena. We will illustrate the development of a new finite element methodology to model them. This new methodology is based on a level-set framework to model deformation and the ad hoc interfaces kinetics. We will focus on the modeling of surface diffusion at the α/β phase interfaces and motion by mean curvature at the α/α grain interfaces.

The single point incremental forming process is perfectly suited for the forming of titanium prostheses. However this process suffers from not homogeneous thickness distribution. Moreover considerable forces can occur. In this paper, a numerical approach is proposed to minimize the maximum forming force and to maximize the minimal thickness of titanium sheets. A surface response methodology is used to find the optimal values of two input parameters of the process, the punch diameter and the vertical step size.
An advanced numerical methodology is developed for metal forming simulation based on thermodynamically-consistent nonlocal constitutive equations accounting for various fully coupled mechanical phenomena under finite strain in the framework of micromorphic continua. The numerical implementation into ABAQUS/Explicit is made for 2D quadrangular elements thanks to the VUEL users’ subroutine. Simple examples with presence of damaged area are made to show the ability of the proposed methodology to describe the independence of the solution from the space discretization.
Nowadays Steel is being substituted for aluminium to reduce weight of automobile. Widely applied production method of aluminium component has been casting process or cast/forging processes. But casting or cast/forging processes have limits of application to part which is required high strength durability like automotive component. In this study, flow forming process has been adopted to produce aluminium transmission spline parts to ensure required mechanical properties.
Dividing samples into small areas according to their microstructures and assigning individual properties to each small area are a possible access to micro forming simulation considering material size effects. In this study, a new model that includes grains and grain boundaries was developed based on the measured microstructures of samples. The divided small areas in the model have exact shape and size with real crystals on the samples, and each grain and its boundaries have their own properties.

The aim of the paper is presentation of developed optimization strategies, effective at the optimization of multi-stage and multi-threads chain structures (linear or acyclic tree graphs) with multiple intermediate goal functions. The inspiration for this type of analysis is the production chains often seen in industrial plants. Production in these plants consists of sequences of multiple units connected linearly or in tree-structured graphs in which, at various production stages, intermediate quality criteria, related to the semi-products, may occur.
In a framework considering thermodynamic of irreversible process, Eulerian constitutive models for elastoplasticity in large deformation are proposed. A formalism of four-dimensional equations derived from the Theory of Relativity is applied to ensure the generality and covariance of the model. The Lie derivative is also chosen as a true time derivative to verify the covariance and thus material objectivity. 3D models are derived from 4D equations and compared with classical ones by applying in the forming process simulations.
Based on semi-solid forming theory, a novel energy-efficient route called soft-core forging under ultra-high temperature was proposed in open die forging process. To verify its feasibility for industry manufacturing , series of pilot tests(weight 500kg) were carried out in heavy plant. Here, the effects of parameters such as solid-liquid fraction on the microstructure, macrosegregation and mechanical properties of Cr-Mo-V steel were studied experimentally. The microstructure characteristics and mechanical properties such as hardness, tensile strength of specimens exhibit the same tendency.
A crystal plasticity model is adapted in order to predict strength, internal stresses and texture development in pearlite. The model is used as the user-defined material law in macroscopic finite element simulation of rolling. It is shown that the material response depends strongly on the reorientation of cementite lamellae. The model produces good estimates of the lattice strains measured by neutron diffraction as well as the uniaxial tensile curve.

The efficiency of any numerical scheme measures on the accuracy of the scheme and its computational time. An efficient meshfree augmented local radial basis function (RBF-FD) method has been developed for steady incompressible Navier-Stokes equations in spherical geometry with unbounded domain. The axi-symmetric spherical polar Navier-Stokes equations are solved without using transformation. The non-linear convective terms are handled efficiently by considering upwind type of RBF nodes. The developed scheme saves 50% of the CPU time than the usual RBF-FD method.
A new simulation environment is developed to simulate the evolution of microstructure and the corresponding flow stress during rolling and softening. An orientation dependent crystall plasticity hardening model is coupled to grain evolution-, recovery- and recrystallization kinetics within the three dimensional phase field framework. Kinetics are treated consecutive to differentiate between individual hardening and softening effects. Simulation experiments are compared to hot compression tests at 1100°C with a strain rate of 1 s-1.
In prestressed machining superalloy, due to the complicated contact loading at the tool-
chip interface, ceramic tool wear is rare difficult to evaluate only by experimental approaches. The overall objective of this
study is to develop a methodology to predict the tool wear evolution in
prestressed machining superalloy using combined FEM and DEM simulations. The
results show that higher cutting speed effectively results in slighter wear of Sialon
ceramic tools, and deeper depth of cut leads to more serious tool wear.
The warm deep-drawing process of laminated sheets consists of aluminum alloy series 1050, 5052 and stainless steel 304, experimentally. To survey the thinning behavior in laminate sheet during warm deep-drawing process; three blank temperatures namely, 25̊ C, 100̊ C and 160 ̊C are examined. Moreover, to obtain different grain sizes, the aluminum sheets are annealed at 350̊ C, 400 ̊C and 450̊ C for 1 hour. Furthermore, influence of temperature and grain size on variation of thickness is surveyed.
Traditionally, combination of equivalent plastic strain and stress triaxiality parameters are taken into account when performing characterization of material ductility. Some well-established models like Lemaitre model, GTN based models and many others perform relatively well at high-triaxiality stress states but fail to give adequate answers to low-triaxiality states. In this work, three damage models are presented, applied and assessed to a cross-shaped component. Concerning material, AA5182-O, corresponding damage parameters are characterized by an inverse analysis procedure for each damage model.

In this work, a Meshless approach for nonlinear solid mechanics is developed based on the Element Free Galerkin method. Furthermore, Meshless is combined with an elastoplastic model coupled to ductile damage. The efficiency of the proposed methodology is evaluated through various numerical examples. Besides these, two-dimensional tensile tests under several boundary conditions were studied and solved by a Dynamic-Explicit resolution scheme. Finally, the results obtained from the numerical simulations are analyzed and critically compared with Finite Element Method results.
Scaled experimentation founded on dimensional analysis has a long history but has to-date achieved little success in complex metal-forming applications. This is particularly true for thermo-mechanical processes, where scaled experimentation is recognised to provide little insight. It is shown in this paper that current similarity approaches in continuum physics can be overly prescriptive. The concept of finite similitude is introduced, which is shown to be better suited to finite-element analysis for the design of scaled experiments.
A three-dimensional finite element model of cold pilgering of stainless steel tubes has been developed to increase the understanding of forces and deformation during the process. The focus is on the influence of vertical displacements of the roll stand and axial displacements of the mandrel and tube. The displacements of the rigid tools are achieved by supporting them with elastic springs. A sensitivity study is performed to investigate the influence on the contact surface, strain path and roll separation force.

We propose a 3D h-adaptive methodology dedicated to the simulation of metal forming processes involving ductile crack initiation and propagation. Cracks are represented by fully damage tetrahedron deletion. Specific smoothing tools of the surface crack inspired by subdivision line and surface techniques will be presented. Element size inside the domain and along the crack path is driven by error indicators based on the derivatives of physical quantities calculated by diffuse approximation. The procedure is integrated in Abaqus explicit.
A thermodynamical framework is presented to derive regularisation operators in micromorphic continuum media displaying elastic-plastic and damaging behaviour at large deformation. Three alternative finite deformation frameworks are successively applied: decomposition of a Lagrangian strain into elastic and plastic parts, use of a local objective frame and multiplicative decomposition of the deformation gradient. In each case, nonlinear generalizations of the well-known Helmholtz regularization operator are derived and compared.
This paper presents a new approach based on a fully coupled procedure in which the lubricant flow and the plastic deformation of the metallic material are solved simultaneously. The approach is applied to strip reduction of a sheet with surface pockets in order to investigate the escape of the lubricant from the pocket by means of Micro Plasto HydroDynamic Lubrication (MPHDL) and Micro Plasto HydroStatic Lubrication (MPHSL) mechanisms.
This paper investigates the formability effects of variable blank holder force on deep drawing of AISI 304 rectangular cup. Various sets of blank holder forces were set to observe the formability, which was indicated by the percentage of sheet thinning in this study. The results showed that the blank holder forces at the locations of the sheet edges surrounding the cavity areas were considered dominant to reduce sheet thinning and enhance the formability.
Fracture prediction in blanking has gained great attention due to increasing requirements of high-quality products. In this work, the predictive capabilities of different uncoupled and coupled damage models, recently implemented in a fully implicit homemade FE code, for blanking process are compared. Some advanced models considered here include damage sensitivity to both triaxiality and Lode angle in their formulation. Adoption of a constant or variable cut-off value of triaxiality for fracture is analyzed. Finally, numerical and experimental results are compared.

This work presents an algorithm to solve thermomechanical problems, based on a staggered coupling strategy. This kind of strategy partitions the overall problem into a heat transfer problem, at a fixed configuration, and an elastoplastic mechanical problem, at a known temperature. The time step for both problems is controlled with an R-mim strategy, which permits an increment of time variable along the process. This study focuses on the optimization of the limits for the variables that control the R-min strategy.
Most of the stages of material behavior can be described by means of continuous models but they fail to give an adequate answer when initiation and propagation of cracks occur. Continuous-discontinuous approaches can be adopted resorting to different techniques like element erosion, remeshing or X-FEM techniques. Here a new continuous model approach based on the phase field theory is extended to ductile failure. The phase field variable describes the damaged zone and its evolution is associated with standard damage models.
Standard friction models do not take the process parameters temperature, velocity and surface pressure entirely into account. To describe the friction conditions during extrusion processes, the impact of all process parameters has to be considered. A remarkable influence of pressure and temperature on friction is experimentally detected whereas the influence of sliding velocity is small. In the framework of the conference the experimental results, the subsequent modelling approach as well as FE simulation results will be presented and discussed.
This article presents the results of FE modeling of a fundamentally new combined process of plate rolling and stamping. This process was first used to produce large-sized bodies of revolution, such as the bottom of a vacuum vessel, bottom of a ladle furnace. Traditionally, such products (with the wall thickness exceeding 40 mm and the diameter/width of up to 4000 mm) are produced in machine-building enterprises using stamping processes. Were investigated various schemes of implementation of the combined process
A new design of cruciform type specimen for uniaxial stretching is proposed to test formability with strain ratios in the range of from shear to tension.The forming limit of a DP 980 steel sheet was determined with strain ratios from −1≤ε2/ε1 ≤1. Then the experimental results were drawn in both ε1- ε2 and εeq- σm/σeq spaces, and the theoretically predicted results based on Hill, Swift, M-K, Storen-Rice and Hora instability models were compared with the experimental ones.

Sheet-bulk metal forming allows the manufacturing of sheet metal parts with integrated functional elements. The investigated process combines deep drawing and upsetting. The occurring 2D and 3D stress and strain states lead to challenges regarding material flow control due to different geometries of functional elements. The numerical analysis shows the transferability for the results of the different functional elements for their combination and the interaction between those functional elements regarding the material flow. The results are validated by experimental tests.
Roll bonding is a well-known process to produce composite sheet metals. Applying to ring rolling would allow to produce seamless radial composite rings, which combine the advantages of different material properties. This process is studied, both experimentally and using FEM-simulation. For the FEM an explicit model is applied including the kinematic control algorithms of the radial-axial ring rolling machine. In the used model the occurrence of unexpected asymmetrical joints can be reproduced, which are observed during the rolling experiments.
A frequently applied mapping method for a ductile fracture model from stress space to strain space is based on the isotropic von Mises model which is not always consistent with non-quadratic yield criterion used for modeling of ductile fracture. The proposed research work demonstrates a general procedure which can be incorporated with any yield criterion in ductile fracture mechanics. A new mapping method of fracture model from stress space to strain space has also been formulated in this study.

The first 3D FEM developed by Prof. Chenot in the late 70s was devoted to hot rolling and the spread (slab widening) phenomenon, for which the Upper Bound Method had showed limitations, at least under the form used at the time. It is therefore fit to sketch the time evolution of rolling models, their evolving ambitions, to locate Prof. Chenot's and CEMEF's contributions before evoking the present trends and future demand, revisiting the debate between FEM and simple methods
Ti6Al4V is one of the most frequently used materials for biomedical applications due to its biocompatibility and excellent mechanical properties. However, wide usage of Ti6Al4V is limited by its poor room-temperature formability. Therefore, hot Single Point Incremental Forming(SPIF)has been used to improve its formability.This paper aims at proving numerically the feasibility of the hot SPIF of an acetabular component of hip prosthesis.The effect of the forming temperature on the geometric accuracy and the failure of the final product is investigated.
The main goal of the research is development of the integrated method for determining the formability characteristics of porous materials for application in modelling and computer simulation of metal forming processes. Particular attention is put on implementation of a complete digital material representation model replicating complex morphology of sintered porous microstructures for subsequent micro and multi scale analysis of deformation. Discrete modelling approaches namely cellular automata/Monte Carlo method will be used to develop digital material representation models within the work.
In the past couple of decades, the casting industry has been substantially relying on simulation software to improve the as-cast product quality. However, accurate predictions are often difficult, due to the complexity of phase properties evolution during solidification and subsequent solid-state transformations, especially for multicomponent alloys. In the current paper, we aim to alleviate these difficulties by coupling THERCAST® casting simulations with thermodynamic and thermomechanical data, made available by JMatPro®. The approach is particularly suited for predicting chemical segregations.
In this study, the electron beam welding(EBW) is applied to manufacture the automatic transmission parts. In order to evaluate on the characteristic of electron beam welding, an experiment is performed according to conditions on characteristic of bead width and penetration depth. Also, in order to apply the automatic transmission parts of EBW, the experiment is performed. In order to apply the EBW of automatic transmission parts, the process conditions of EBW to satisfy of product specification were derived.

The hybrid model of tool material deterioration is proposed. It accounts for various mechanisms, including abrasive wear, adhesive wear, thermal fatigue, mechanical fatigue, oxidation and plastic deformation. Individual models of various complexity were used to simulate separate phenomena. The strategy of combination of these models in one hybrid system was developed to account for the synergy of various mechanisms. The physical simulations of hot forging were used to supply the data for identification of models.
The finite element analysis is carried out into the simulation of the sheet metal forming process in order to confirm the applicability of the solid element. The simulation investigates the prediction accuracy of earing and springback as well as the overall deformation mechanism in the conventional deep drawing process. The analysis of the stamping process for the front lower arm in the automobile is also carried out in order to predict the shear fracture originated from the sheared edge.
A new 2D constructive algorithm, called Advancing Layer Algorithm, for the generation of dense ellipse packing is proposed. The method allows to respect the imposed area, shape ratio and spatial orientation distributions (i.e. the inertia tensor) and achieves high packing densities. Thanks to an approximation of each ellipse by a set of circles, cost of this algorithm remains reasonable and can be easily immerged on FE mesh. Morevover, non-equiaxed polycrystalline microstructures can be generated thanks to this approach.
A multiphase model considering shrinkage induced-flow, solid grain sedimentation, thermo-solutal convection is used to predict macrosegregation in a 36-ton steel ingot. Measurements, including the temperature records at the mould-ingot interface, macrostructure detection, and solute concentration distributions, are conducted to acquire the relevant calculation parameters for the 36-ton steel ingot. Interfacial balance is adopted to build constraint between different solute element evolutions. Good agreements are obtained for comparisons between predictions and measurements of solute variations along selected lines.
Plastic deformation in metallic alloys is heterogeneous by nature. Compartmentalized models have been developed in order to overcome the flaws of classical homogeneous models by taking into account a certain amount of heterogeneity in the plastic behavior by means of compartments with specific behavior. In this work, we show how this heterogeneity can be tailored to fit the behavior of various metallic alloys. The choice of the local behavior of each compartment and the distribution of the heterogeneities are debated.

Extruded profiles are widely used but their design is still difficult. Several parameters have to be considered. This is particularly true when complex geometries, i.e. non- symmetric or hollow profiles have to be obtained. A novel metamodel technique was proposed to define the relationship between input and output process parameters in porthole die extrusion. An iterative dynamic DOE was finally used to improve the accuracy of the model around the most promising area of the process domain.
Numerical simulations have been carried out for multi-stage hydro-mechanical deep drawing of a part with hemispherical bottom from Inconel 718 sheets using FEM. Process parameters such as peak fluid pressure, pressure path, draw ratio, blank holding force and coefficient of friction have been optimized to reduce thinning in the final part and enhance formability. It is also shown that the part can be drawn to the desired depth in less number of drawing steps when compared to conventional deep drawing.
This paper shows an analysis of the transient dynamics during the dissimilar joining process of aluminum-steel along with a comparison of the final results with experimental data. The development of a multiphysical model within OpenFOAM® simulation software comprising diffusion and reaction physics allowed to simultaneously obtain both, macro- and mesoscale effects, such as the surface wetting and the growth of the intermetallic layer.
In this work, we aim to simulate the effect of local particles concentration on the macroscopic flow in an industrial part. We present a migration prediction method for highly loaded fluids with large spherical particles. Migration computation is coupled with Navier-Stokes resolution, by adding a local viscous term and a frame invariant extra-stress term. The implementation in the Rem3D® simulation software enables us to realize several validations, from simple analytical case to more complex and three dimensional industrial cases.
Bezier curve has been widely used as the roller path in conventional spinning. In this paper, Finite Element model with parameterized 2-pass conventional spinning toolpaths based on quadratic Bezier curve is developed to explore the influence on the wall thickness reduction of spherical components. The results show that the first path has significant effect on wall thickness distribution and the selection of parameter values in toolpath is crucial for thickness distribution.

Inverse form finding – as a type of shape optimization – aims in determining the optimal design of a workpiece for a specific forming process. Recently, a novel parameterfree approach was developed and benchmark tests already delivered promising results. As a feature, a coupling to an arbitrary finite element software is feasible in a non-invasive fashion. The aim of this contribution is to investigate the effect of kinematic hardening and cyclic loading to the convergence behavior of the algorithm.
Metallic materials microstructure is essential if one wants to predict accurately ductile fracture under complex multiaxial and non-proportional loadings. An advanced finite element approach based on level set functions and body-fitted immersed meshing capabilities enable the modeling of nucleation, growth and coalescence mechanisms for complex 3D microstructures and under large plastic strain. Applications on real microstructures (coming from in-situ laminography) and exact boundary conditions (thanks to Digital Volume Correlation) are studied and discussed for different loading conditions.
Engine gasket is thin steel plate with coatings. Its compression deformation affects the height of engine assembly, which changes combustion volume and then influences engine performance. In this paper, the assembly simulation of head, block and gasket was studied. Then a further gasket’s partial micro-model in micron-scale meshes was established to analyze the thin coatings. Deformation of each gasket layer was analyzed and more precise results were obtained during simulations. Lead pellet tests were done to verify results of simulation.
An Eulerian finite element approach was used to predict material flow and temperatures during friction stir processing (FSP) of 304L stainless steel. Steady-state temperatures and strain rates allowed for estimates of recrystallized grain size in the stir zone. Temperature predictions were accurate to within 4% in the plate, compared to experimental measurements in three locations. Recrystallized grain size predictions were also reasonable compared to experimental measurements. Model results will be used to establish relationships between FSP conditions and resulting microstructure.
A series of Cu-Cu compressed isothermally experiments were designed to investigate the effect of dynamic recrystallization on interface bonding during plastic deformation process. The hot compression tests were carried out at temperature range from 750 ℃ to 900 ℃ at strain of 0.10, 0.20, 0.40 and 0.60 with strain rate of 0.1 s-1. Dynamic recrystallization was characterized by optical microscopy. It appears that along with the increase of the deformation and the compression temperature, the better the interface bonding degree.

The production process of car structural components can affect their crashworthiness owing to the introduction of modifications in the material characteristics during the sheet metal forming process. The deep drawing and the subsequent operations induce material work hardening, sheet thickness variation and geometry variation. Such modifications are not uniformly distributed and may relevantly affect local features. As a consequence the forming process of a component results to have an impact on the vehicle crashworthiness.
Several models are combined in FE analyses of a thin aluminum CT specimen: polycrystalline model for plasticity, PLC model, porous plasticity and Coulomb fracture models. Multiple strain bands are obtained, similar to the ones observed in laminography with 3D digital volume correlation. Strain rate bands appear and vanish in relation with the load-displacement curve serrations. Crack propagation occurs during strain rate surges. The strong relation between the PLC phenomenon and the transition from flat to slant ductile fracture is emphasized.
The molecular-dynamics analysis is presented for 3D-compaction simulation of nano-crystalline metals under cold-compaction process. The EAM pair-potential is employed to model the formation of nano-crystalline-particles at different temperatures and rates-of-deformation in die-forming process. The die-walls are modeled using the Lennard-Jones inter-atomic-potential between atoms of nano-powders and die-walls. The results of atomic simulation are compared with experiments for densification behavior of nano-powders. It is shown that the proposed molecular-dynamics simulation can be efficiently used through a multi-scale modeling of powder-compaction forming.
In this study, CFD based numerical model is developed to predict the temperature distribution and material flow during FSW of aluminum alloy 2017A.The main objective is to gain a better understanding of the flow of material around a tool, which leads to a good estimate flow and temperature. These results were obtained using a viscosity which is near the solidus softening.
Currently hot rolling plants are entering the market segment for thick gauges and high strength material where the elastic bending property of the strip leads to internal forces in the coil during coiling operation. The strip tends to open.. Primetals is investigating several possibilities to facilitate safe coil evacuation and coil handling under spring-back conditions. The contribution includes finite element models of such mechanical solutions, and results of parameter variation and stability limits of case studies are shown.

In the aerospace industry, there is a great need for new materials which exhibit improved mechanical properties, increased tensile strength, hardness, and toughness at a reduced weight. A brief introduction of severe plastic deformation (SPD) is presented along with different processing techniques for producing nano-structured materials through SPD. Finite element modeling and simulation of Equal Channel Angular Processing (ECAP), High Pressure Torsion (HPT), Twist Extrusion (TE) and Repetitive Corrugation and Straightening (RCS) is attempted and the results are discussed.
A typical part of B1500HS steel was formed using hot stamping tools. Effect of austenitization temperature on microstructure and mechanical properties was studied by experiment and finite element methods. Temperature of steel plate has a significant effect on the temperature of hot stamping tools, and the temperature of punch rises at a faster speed than that of die. The austenitization temperature and time both have significant effects on the size of martensite, but have not obvious effects on the hardness.
Fluid dynamic method is applied to investigate the influence of size effect on bearing capacity and other performances. Reynolds equation is modified by adopting
velocity slip boundary condition.The sensitivity factors are used to make a quantitative and qualitative analysis. Simulation results show that size effect will affect bearing performances to a certain degree and the effect curve of size effect on bearing performances are given. The four maximum oil film pressures reduce with the increase of slip length.
Numerical Simulations shaping thin sheets of Stainless steel are becoming increasingly important in the design phase and processing into finished products. These simulations are often penalized by a too brief description of the plastic behavior and in particular the anisotropy of rolled sheet. This is why it is important to model the behavior of the structure during the formatting including stamping.

Manufacturing of multi-phase steel products was analysed. Various thermal, mechanical and microstructural phenomena occur during production cycle and various models, including multiscale ones, are applied to simulate this cycle. Problem of optimization of the manufacturing chain with the required product properties introduced in the objective function, was considered. Various optimization techniques were used having in mind complexity of models and computing costs for each process in the chain. Sensitivity analysis was performed and the best optimization strategy was proposed
The numerical analysis which involves phase transformation needs mathematical modeling of thermo-metallo-mechanical couplings. In this study, finite element simulator has been developed to predict volume fraction of micro structure of low alloy steel and its hardness during rapid cooling process. Diffusional and non-diffusional kinetics for phase transformation are implemented into commercial finite element simulator AFDEX. To verify the developed simulator, Jominy tests and its FEM simulations has been conducted.And finally, the prediction model of hardness is presented.
The manufacturing process and the behavior of a spring manufactured from an aluminum sheet is described and investigated in this work considering the specifications for the in-service conditions. The spring is intended to be applied in car multimedia industry to replace bolted connections. Among others, are investigated the roles of the constitutive parameters and the hypothesis of evolutive elastic properties in the multi-step forming process and in working conditions.

The forming limit diagrams (FLDs) of sheet metals with FCC (AA5182-O) and HCP (AZ31B) crystal structure are calculated by combining visco-plastic self-consistent (VPSC) crystal plasticity method with the Marciniak-Kuczynski (M-K) model. The simulated FLDs after different paths of prestrain loading are also compared with the experimental ones. The predictions with current method can match the experimental FLDs of different structures well.
Hollow or tubular pre-products are used to meet lightweight requirements and to reduce production cost of cold formed components. To increase efficiency of manufacturing, a combined forming process was developed and is shortly presented in this paper: Manufacturing of hollow pre-products by combining the processes of backward cup extrusion and piercing. Disclosed work consists of numerical identification of significant process input variables, process outcomes and the process limits, as far as the combined forming process is concerned.
In this work an integrated model for all the process of glass forming of glass containers is presented. The model addresses press-and-blow and blow-and-blow procedures from the gob forming to the final product. Glass forming involves coupled thermal-mechanical physical phenomena, in which the material viscous flow is highly dependent on heat transfer which, in turn, is dependent changes of shape due to material flow. Numerical aspects associated with the model implementation and its validation with real formed products are discussed.
The aluminum alloy Al 7075 is a structurally hardened alloy and not by hardening. These mechanical properties are of particular microstructure obtained by thermo-mechanical treatments. Among other things, this is complicated microstructure which is responsible for the mechanical performance. The hardening phases are obtained by precipitation sequence that evolves with changing mechanical characteristics during the maturing time. Following heat treatment, carried out on this alloy, the evolution of the mechanical properties of Al7075 is very dependent on aging time parameter.

This work is devoted to the simulation of new energy-saving combined process "helical rolling-pressing" in program Simufact Forming. During the simulation were studied the main parameters of stress-strain state and microstructure. The variation of the main technological parameters showed that the influence of the heating temperature of the workpiece plays a significant role in the degree of grain grinding. While the speed of deformation, allowed by the mill design limits, has no significant effect on the microstructure.
Micro incremental sheet forming is investigated as a method to validate the constitutive model of material. This optimization is based on a reverse identification scheme. Numerical simulations are performed and compared with experimental tests, in order to have a corresponding model of material. Within further investigation into the numerical model, a sensitivity study is done on some geometrical parameters (e.g. uncertainty about tool’s geometry or experimental test parameters) in order to evaluate the impact on the corresponding model of material.
The use of CFRP is increasing markedly, especially in aviation industry, but CFRP sheets cannot be formed by press-forming techniques due to its low ductility. Since the mechanical characteristics of CFRP is dominated by the microscale structure, it is possible to improve CFRP's formability under optimum material structure. Therefore, to improve formability, the interaction between the carbon fiber and the matrix has to be revealed. In this study, mesoscale analyses have been conducted by FEM with cohesive zone elements.
During ultrasonic welding, microstructural changes occur due to the coupled effects of severe plastic deformation (SPD) and frictional heat generation. Theory of the microstructural evolution was for the first time hypothesized as three regimes, namely SPD, dynamic recrystallization (DRX) and grain growth according to the material thermomechanical loading conditions. A 3D metallo-thermo-mechanically coupled model was developed in DEFORM to model the temperature-dependent mechanical deformation and microstructural evolution during the ultrasonic spot welding process.

A numerical model was established to investigate the micro hydro-mechanical deep drawing process of austenitic stainless steel 304 foil. Due to the miniaturisation of the specimen size, the effect of grain size, gap distance and radial pressure during drawing process could be prominent. The results indicate that the appropriate radial pressure and gap distance could improve the limit drawing ratio (LDR) of manufactured cylindrical cups by reducing the friction resistance.
Precise hardness and phase prediction for quenched steel with the fe-method requires material data, which is usually obtained from measured CCT-diagrams. However, most software packages require TTT-diagrams, which can be calculated from the chemical composition of the material or converted from existing CCT-diagrams. With both methods the numerical prediction often results in deviations to reality. A new optimization method can improve the accuracy of phase content and hardness prediction by optimizing the TTT-diagram with measured data of controlled quenching experiments.
This work aims to model and to simulate the polyurethane foaming process. Models taking into account the two main chemical reactions of the formation of polyurethane, the exothermic effect of these reactions as well as the thermo-rheo-kinetic coupling characterizing this process are proposed and implemented in the software NOGRID-points based on a meshless method (FPM). We also propose a prediction of some acoustic foam characteristics based on the results of the numerical simulation of the foaming process and semi-phenomenological models.
The complex material flow occurring during the weld of dissimilar AA2024 to Ti6Al4V butt and lap joints was highlighted through a dedicated numerical model able to take into account the effects of the different materials as wells as the phase transformation of the used titanium alloy.

Even though there are substantial progresses on the establishment in terms of the DRX principles and evolution with the view point of the materials science, an appropriate flow curve modeling for the finite element analysis has been deficient to take into consideration of softening behavior. This paper mainly concerns the material modeling of Mg alloy at the elevated forming temperature in terms of thermomechanical flow curves, which enables implementation of flow curve softening in the finite element analysis, efficiently.
Recently, composites based on thermoplastic resins have emerged for structural applications. Although they might not completely replace thermosets, those materials offer potential advantages for demanding applications. During thermoforming process, the cooling rate of the material is the primary process variable as it governs the crystallization of the matrix. A crystallization model derived from Nakamura’s work has been implemented into the thermoforming finite element code PAM-FORM. Coupled with heat transfer equation, it permits a good description of the crystallization event.

In order to accelerate the design and production of new products using enhanced materials, it is essential to improve the modeling of materials behavior within a whole chain of simulations starting from the early stages of materials transformation and going through cold and hot forming stages, heat and surface treatments, joining steps and finally ending up with the prediction of components behavior under realistic in-use loading conditions. The overall strategy and various applications are presented and future challenges are discussed.
The standard Gleeble max-strain unit has been modified to also allow axial elongation. Analyses indicate that both positive and negative hydrostatic stresses can be achieved during forging simulations, depending on the amount of strain per hit. This opens the way to the study of the effect of hydrostatic stress on development of damage and healing. In this contribution we will show results of finite element simulations of this test at different settings. Experiments seem to confirm these results.
The exhaust manifolds of steel pipe are formed with multiple bending operations. The pipe bending process is complicated and the forming conditions such as controls of pressure are significant. Failure shapes like rupture or wrinkling were found in some load conditions. Therefore, this paper presents the formulation of several finite elements for simulating and optimizing pipe bending process using FE-explicit method. The analyzed results were compared with the experimental thickness and the performance and accuracy were examined.
Spallation of oxide scale was analyzed by FE simulations. Three factors contributing to the interface fracture, ie., thermal expansion mismatch, stress relaxation and the geometry of interface, were investigated. Particularly, stresses near interface were analyzed. Thermal and mechanical properties of substrate and oxide scale were measured, and fracture property of interface to describe the spallation behavior was inversely determined by the scratch analysis. The effects of the interface geometry and oxide thickness on the spallation during bending will be discussed

This study was to evaluate the residual stresses of FSW welding magnesium alloys (AZ31). The results show that the FSW processes lead to the formation of several distinct zones with differing mechanichal properties. The residual stresses evolution have been explained by the heterogeneous modifications of the micro structure, in particular a marked decrease in the grain sizes, a high modification of crystallography texture and also by the different anisotropic properties resulting from plasticity in the case of the FSW process.
The damage evolution of high strength steel at elevated temperature is investigated by using the Gurson-Tvergaard-Needleman (GTN) model. A hybrid method integrated thermal tensile test and numerical technique is employed to identify the damage parameters. The analysis results show that the damage parameters are different at different temperature. Furthermore, the calibrated damage parameters are implemented to simulate a bulging forming at elevated temperature. The experimental results show the availability of GTN damage model in analyzing sheet formability in hot forming.
Aiming to find out the optimum conditions in the simulations of sheet metal forming, by mean of finite element analysis and running softwares with explicit dinamic solutions, this work studied the conditions in which the employment of scaled models could be useful in order to reduce the costs in terms of computational effort. The used methodology allowed to better understand the limits in which this approach is valid, in order to get the computational cost decreasing.
The authors have developed a novel material model based on non-associated flow rule and stress-rate dependent constitutive law, where the yield function and the plastic potential function are defined with different arbitrary-order functions. Advantages of this model are for anisotropic sheet metals and large deformation leading to fracture. In this study, effects of the order of the yield function and the plastic potential function on the fracture limit prediction have been numerically investigated.

The aim of this work is to present and compare two numerical modeling approaches for the simulation of residual stresses caused by the welding process. In the first approach, the coupling of the different material states is ensured using an ALE method. The molten pool and the fluid flows are modeled. However in the second approach, numerical simulations were carried out in the context of Lagrangian approach where the fluid flows in the weld pool are not accounted for
Multigrid methods are known for their asymptotic efficiency when solving large linear systems. The developed hybrid method is based on both a geometric approach, by generating different levels of meshes, and on an algebraic formulation by using the Galerkin approach to generate coarse matrices. Generation of grids, operators and matrices is fully automatic and compatible with remeshings and parallel computing. Resulting multigrid solver is integrated within the FORGE® package and its efficiency is validated on several industrial bulk forming problems.
Fully coupled anisotropic constitutive equations with mixed nonlinear hardening and isotropic ductile damage, is improved by considering the distortion of the yield surfaces. A convenient “distortion” deviatoric stress tensor is used in both yield criterion and plastic potential instead of the usual classical deviatoric stress. A parametric study is conducted under simple loading paths in order to explore the capabilities of the model in describing the yield surface distorsion. Comparisons with experimental results on aluminum alloy are also given.

Method of quantitative evaluation of shape of a creep curve and extrapolation of creep
curve based on the concept of “SATO-Index” is presented. Shape of a creep curve can be quantitatively evaluated by the index, and a
differential equation with a set of four independent characteristic values represents
an entire creep curve. One characteristic value reflects strain dependence of strain-rate. Typical applications on simple alloys
such as solid solutions and some engineering alloys are presented.
To reduce springback, coining process is often applied in sheet metal forming. But,the
finite element method with conventional shell element can’t formulate this process
because of plane stress condition. Therefore, in this study, a new shell element which has
extra nodes called pseudo-nodes to calculate through-thickness stress is developed. Using this element, a mechanics-based springback compensation system has been constructed
and tested.

The mechanical properties of Aluminum alloy Al2024 are of particular microstructure
obtained by thermo-mechanical treatments. The hardening phases are obtained by
precipitation sequence that evolves with changing mechanical characteristics during
the maturing time. Following heat treatment, the evolution of the mechanical properties of
Al2024 is very dependent on aging time parameter. An experimental test of traction
in different companion of Al2024 treated (quenching) is our first database to fully describe the kinetics of precipitation and
changes in the mechanical properties.
This paper focuses on the effect of material flow over die radius and the corresponding cycle of deformation. First, we describe an
original model for the prediction of residual plastic deformation and stresses in the blank section. This model, working on a
scale ten times smaller than the element size, has been implemented in SIMEX, one-step sheet metal forming simulation code,
leading to a great improvement of the accuracy of the solution. Finally, we discuss
springback applications.
A coupled thermo-mechanical framework is adopted to analyze Friction stir welding (FSW) problem. Use of first order time
integration technique for the solution of the transient problem is not advantageous, as it obliges the modeler to use small time-steps to deal with high rotational speed during the
process. In this work, a high-order time integration method is considered for both
transient and convective terms. This allows the use of larger time-steps and speeding up the simulation while increasing the accuracy.

Champagne
Tasting Party
Date : Monday, July 4th 2016
Hour : 20:00 – 22:00
Place : The Tools and Trade
Museum/ Maison de l’Outil et
de la Pensée Ouvrière (see map)
About The Tools and Trade Museum After the 1524 fire, Jean Mauroy, the inspector of aids and tallages for the kingdom, had the Hôtel de l’Aigle built and lived there with his wife Loyse de Pleurre. It then was named the Hôtel de Mauroy. At their death, they bequeathed their estate to the founding of an orphanage (1582), directed by the Friars of Trinity.
In 1746, the home received the first power looms and became the largest manufacturer of stocking knitting machines in the city. In 1789, it was turned into a garrison and then a mill and later became the first listed historical monument in the Aube department. From 1920 to 1962, it housed a print shop, then it was bought by the City of Troyes in 1966 and entrusted to the Association Ouvrière des Compagnons du Devoir du Tour de France for restoration.
Starting at this time, collections of tools, books and histories were stored there, donated by the Révérend Paul Feller, a Jesuit and teacher seeking to reform teaching methods.
(1913-1979). Inaugurated in 1974, the Maison de l’Outil et de la Pensée ouvrière (Tools and Trade Museum), named thus by P. Feller, exhibited in this superb setting of the Hôtel de Mauroy an incredible collection of more than 10,000 objects and tools used in traditional trades. The museum explains the use and symbolism of the creations in stone, wood, iron and glass, designed and made by the highly-knowledgeable creators and artisans.
The ambition of the museum is to contribute to the interaction between man and matter, between manual and non-manual, between thought and tools. Used, engraved, personalized and transformed, these tools will always be animated objects, reflecting the memory of their worker companions. It is an ode to manual labour and creation.
The Centre de ressource has more than 33,000 books and magazines containing invaluable worker and technical material. (www.mopo3.com)

About a hundred hectares devoted to sharing expertise and harvests, highlighting the specific character, the authentic spirit and true identity of De Barfontarc champagne.
With extreme precision and perfect knowledge of the terroir the oenologists of our House have composed the harmony of each and every vintage wine by pressing the juice out of each bunch of grapes.

2. A Guided Tour to The Charles de Gaulle Memorial:
The Genesis of the Memorial Much more than a traditional presentation of the man who launched the "Appeal of the 18 June" or of the first President of the 5th French Republic, the Memorial constitutes a true rendezvous with 20th century history and an encounter with Charles de Gaulle.
Considered as the pedestal of the Cross of Lorraine, the building takes in the character of Charles de Gaulle at the heart of modernity and in the landscapes of Colombey-les-deux-églises, for which he had particular affection. It was in this village that he decided to settle with his family in 1934, and it was here that he made history by greeting the German Chancellor Konrad Adenauer.
His family home, La Boisserie has been open to the public for several decades, but Colombey-les-deux églises has to be visited to gain a better understanding of his character.
The Charles de Gaulle Memorial, by fulfilling this role, adds to the remembrance of this most illustrious of Frenchmen.

Shopping! The "factory shops" were born in TROYES in the 1960s, to sell off local manufacturers' ends of lines. At first only open to factory staff, little by little they were opened to the general public. Let's remind ourselves of some of Troyes great brands: LACOSTE, DD, BABYGRO, ABSORBA, PETIT BATEAU, GIL, MARINER, VITOS... Today, the fame of the "Factory Shops" and the know-how of our Department's manufacturers is second to none. Thousands of visitors from all regions flock to our city to snap up the bargains available: reductions offered vary from 30 to 70% and the number of visitors to these shops is estimated as being close to three million each year. The greatest international brands are now represented. They make TROYES a major centre for Textiles and Clothing, and the true Capital for "factory shops" for personal outfitting. You can thus dress in "chic", "fashion" or "sport" styles according to your needs, with footwear, lingerie and ready to wear available, as well as household linen, etc... in over one hundred shops.
