7.1 Non-linear dynamics of mechanical systems

The numerical and experimental study of non-linear and in particular non-smooth mechanical systems, such as systems with friction, impacts or other constraints are key activities in this sub-theme, and play an essential role in the modeling and analysis of advanced mechanical systems. The research on these phenomena is highly relevant in many engineering applications (friction in high-performance/high-precision systems, drill strings, high-speed milling, hybrid control systems etc.). Numerical aspects are notably difficult, but are becoming more and more feasible with increasing computer power. Related to research theme “Structural Dynamics and Control”

7.2 (Structural) acoustics and noise control, optimization This sub-theme deals with various structural vibrations and the associated sound radiation. The focus is on the one hand on numerical/computational tools for acoustic models, and on the other hand on the experimental validation of those tools. Subsequently, both passive and active means for acoustic noise suppression are investigated. Several mechanical applications are used as benchmark examples, particularly tire–road noise. The development of tools for optimization is essential in the dynamic behavior of mechanical constructions. Related to research theme “Structural Dynamics and Control”

7.3 Vehicle dynamics, tire dynamics and control Vehicle Energy Management Systems Topology Design Research is done on energy management of the complete power train, including the design trade-offs for hybrid vehicles with an internal combustion engine and an electromotor. Advanced model-based optimisation methods, like dynamic programming, are used for the off-line generation of optimal trajectories for the variables that dictate the energy supply from the combustion engine and/or the electromotor. We started a new research project on a hybrid truck. Vehicle Dynamics and Tyres Since 2002, the group has been responsible for the research and teaching in vehicle dynamics. The research focuses on modeling, analysis and control of articulated vehicles, and modeling and analysis of vehicle tires. For the latter, extensive use is made of the flat plank tire tester. The tire research is linked to the tire–road noise research referred to above.

7.4 Mechanical Design and Vision The mechanical design group Construction and Mechanism is jointly headed with Prof.Dr.Ir. M. Steinbuch (Control Systems Technology). Dr.ir. P.C.J.N. Rosielle leads the activities in the C&M lab., which at the moment comprises 7-8 PhD students and about 10 MSc students. Focal point in the lab is the Construction and Design of Advanced, Novel Mechanical Systems. A separate activity mostly directed by prof.dr.ir. P.P. Jonker (part-time professor at the TU/e) deals with Vision in advanced mechatronic systems. Two PhD students and a number of MSc students work in this field. Related to research theme “Structural Dynamics and Control”

7.5 Systems Design Optimization Optimization methods to support systematic design and improvement of complex engineering systems are investigated. We concentrate on simulation-based design optimization in the context of manufacturing system and distribution center networks, manufacturing machines, automotive systems, and micro-mechanical systems. Optimization methods and tools are being developed that can deal with typical governing characteristics such as: one or more computationally expensive computer simulation models in the loop, a mix of continuous and discrete design variables, stochastic design variables and responses, and dynamic response behavior. The development of techniques for approximation, meta-modelling, and lumped-parameter modelling that can be utilized in the optimization plays a central role in our research work. Furthermore, methods for design optimization of multidisciplinary and multi-level decomposed systems have our special interest. Related to research theme "Reliability and Optimization".

7.6 Control of Manufacturing Systems In this subprogramme two main streams can be considered. The first stream considers a class of manufacturing systems that can be approximately modelled by means of a continuous time fluid or flow model. For this approximate model, standard techniques from control theory can often be used to design controllers. As the manufacturing system has a discrete-event nature, a connection between the discrete event plant and the continuous time controller has to be developed. Continuous time signals have to be converted to discrete-events and measurements of discrete states need to be filtered for a better control performance. Currently available flow models often ignore variability, whereas queuing theory often considers only steady state behavior. For that purpose new (mathematical) models need to be developed that include both variability and dynamics. It is clear that preferably these models should be suited for applying standard control theory in order to control these systems. The second stream considers the control of a network of servers through which many types of jobs flow, where it is assumed that servers require a setup time when switching between types. Such networks can be used to model complex communication, traffic or manufacturing systems. Related to research theme “Structural Dynamics and Control”

7.7 Nonlinear and hybrid dynamics In this subprogram two main directions can be considered. First, general questions of nonlinear dynamics and control of mechanical systems including switched (hybrid) systems are studied. In recent years hybrid systems attracted a considerable attention due to possible applications in various fields of science and technology. The theory of

28

hybrid systems is far from its completeness. Therefore it is of interest to further develop methods of analysis and design for such systems. In this research particular attention is drawn to the following two questions: analysis of oscillations in hybrid systems and formalization of some mathematical models of hybrid systems using the formal languages approach. The formal language used is Chi developed in the Systems Engineering group. The second direction of the research is to study applications for the theoretical results in the framework of systems engineering. Nowadays complex manufacturing machines contain discrete-event and continuous-time parts with interactions between the components. These interactions can result in nonlinear dynamical phenomena that should be taken into account during design and real-time control of the machine. This research theme has a strong relation with the topic Embedded Systems (within the Institute for Programming and Algorithmic). Related to research theme “Structural Dynamics and Control”

7. Short description of subprogrammes related to research school EM 7.1 Multi-scale Mechanics & Structure-Property Modelling

This research topic focuses on the mechanical behaviour of solids, with particular emphasis on (1) multi-scale aspects; (2) micromechanical aspects, involving a major influence of the microstructural morphology. Typical topics addressed are single- and poly-crystalline structures, dislocation networks in metals, structured single crystal alloys (turbine blades), structured ceramics, complex structured polymer-metal geometries (flexible displays), (semi-) crystalline polymers with various inclusions, and fibrous materials such as paper(board). The ultimate goal is to arrive at multi-scale solution schemes and physically based constitutive descriptions which can be numerically implemented, enabling an accurate analysis of engineering products or product manufacturing processes.

7.2 Microscopic Aspects of Deformation This research topic aims to provide a sound experimental basis for the computational efforts in the group, through a range of specific set-ups spanning a hierarchy of interacting length scales. Research topics are mainly concerned with the analysis of microscopic aspects of deformation and adhesion at interfaces (e.g. polymer-metal interfaces), of multi-phase materials (e.g. micro-electronics solders), multi-layered structures (e.g. flexible displays), microsystems etc.

7.3 Micromechanics of Functional Devices This research topic focuses on the micromechanics of devices on miniaturization. In miniaturized products, materials cannot be trivially considered as continua. Furthermore, boundary, surface and interface effects play a dominant role. Changes in deformation mechanisms and failure processes directly influence the lifetime of functional devices. Both numerical and experimental tools and techniques are being developed for the analysis of these phenomena and their influence on the performance of microsystems.

7.4 Damage, Fracture and Reliability This research topic focuses on mechanical failure as an important design criterion for metallic products and components. Both prevention and control of damage are thereby relevant. The correct prediction of this ultimate behaviour presents many challenges of both a numerical and an experimental nature. Non-standard continuum theories are required to deal with intense

47

localization phenomena. The transition to discrete failure and the coupling with the underlying microstructure in a multi-scale setting is another goal pursued here.

7.5 Manufacturing and Injury Biomechanics This partly more application-oriented research topic constitutes the group’s link with the Manufacturing and Automotive Engineering Science activities in the Department. In the past period, it has focused mainly on optimal forming processes and passive safety research for automotive applications, i.e. prevention of injuries caused by accidents. The focus for the coming period is the development and use of high-performance materials in manufacturing and automotive applications and multi-scale injury mechanics.

7.6 Swelling Mechanics The mechanics of swelling materials comprises applications in the geotechnical as well as the biomedical areas. Clays, shales, intervertebral disc, cartilage, hydrogels and living cells are a few examples. Mechanical deformations are inevitably coupled to fluid and ion diffusion-convection and to electrical potential gradients and currents in these media. Crack propagation and mechano-transduction are important themes of research.

7.7 New Processes and Devices for Micro- and Nano- Scales

The group research activities are currently clustered in the following activities: Nano-patterning using Charged Particle Beams. In contrast to lithographic nano-structuring techniques using a resist as a pattern transfer medium, a direct modification of thin film materials through particle irradiation can be used. Such a process can lead to unique material properties and surface qualities. Charged particles can either to form small probe beams to be scanned over a surface or broad beam passing a stencil mask before being projected on a surface. The local beam modulation leads to nano-patterns by local conversion of material properties. Micro- & Nano- technologies for bioapplications. In future molecular diagnostics very small quantities of specific biomolecules shall be detected in microliter volumes. In a bead based approach such biomolecules shall undergo a specific binding to nanobeads that can subsequently be detected. Efficient interactions between beads and the fluid can be forced by bead movement induced by magnetic fields or acoustic excitation. Functionalities like mixing of reagents and controlled flow/convection are investigated. Polymer-based micro-devices. Microsystems are traditionally based on silicon technology. Some applications as micro fluidic devices and sensors benefit from the cheap mass production technologies for polymers (micro molding, embossing etc.). Special interest is paid to the design of actuator components which benefit from the possibility of massive parallel operation. This research encounters both the design aspect of the polymer devices and the required fabrication processes. Micro-robotics. This research activity deals with the conception and design of systems and tools for manipulating, positioning and interacting with sub-millimeter size components and parts. It is a highly multdisciplinary discipline that benefits from new development in robotics, material science and micro-fabrication techniques. Our research is currently focused on the development of actuators and sensors for the micro- and nano-scale based on smart materials and on monolithic integration in various substrate. System Integration at the Micro- and Nano- Scale. Scaling effect raises numerous issues for micro-system design: it not only implies the development of novel micro- / nano- fabrication techniques

48

but also requires new design strategies and means to successfully integrate sub-components that constitute the system. Our approach is based on monolithic integration. Multiple functionalities are introduced by locally tailoring material properties. For instance, in glass substrate, we use femtosecond lasers to locally increase the refractive index and the chemical selectivity which allow us to introduce both structural function like flexures or fluidic channels together with integrated optics. Laser assisted carbon nanotube growth. Carbon nanotubes have high potential due to their outstanding electrical, thermal and mechanical properties. For synthesizing the carbon nanotubes a laser based chemical vapor deposition method is used. An advantage of this approach is a high flexibility of the process. The position of the carbon nanotube growth can be chosen and temperature sensitive materials can be used as well, since it is not necessary to heat the whole device. Our research is mainly focused on integrating the carbon nanotubes in flexible electronics as interconnects.

7. Short description of subprogrammes related to research school EM

7.1 Evolving Discontinuities Most physical phenomena are described by differential equations that hold on a finite domain. During the past half century computational physics has developed a host of numerical tools to

57

solve these differential equations, the finite element method being the most prominent. The equations that hold at (moving) interfaces between these domains cannot be solved equally well. Given the ongoing miniaturisation and the wish to understand and to predict the behaviour of materials and devices from more fundamental physical principles, the proper description and simulation of interface phenomena becomes increasingly important. A main thrust of the group is to contribute fundamentally to the development of novel computational techniques for capturing evolving discontinuities. Related to the research theme “Computational and Experimental Mechanics”.

7.2 Computational Multiscale Methods The response of physical systems at the level of practical interest, often called the macroscale, is to a large extent determined by processes that occur at scales which are one to several orders of a magnitude smaller: meso, micro and nanoscales. Two main approaches can be distinguished: (i) upscaling and downscaling, and (ii) computational multiscale methods. In the first category we have computational homogenisation and Reynolds Averaged Navier-Stokes methods as examples for solids and fluids, respectively. The group concentrates on the second approach, including those based on variational or projection concepts, either in solids, fluids, or in interaction problems. Related to the research theme “Computational and Experimental Mechanics”.

7.3 Computational Multiphysics

Increasingly, engineering is confronted with cases where different physical phenomena simultaneously play a role. Examples include durability problems, joining technologies (welding), and many problems in biomaterials. While the stable and efficient solution of the governing equations that describe these phenomena is already difficult, this holds a fortiori in the presence of discontinuities or interfaces. First, the physics of the transport processes in the interface/discontinuity must be captured properly. Secondly, the equations in the interface must be discretised in a manner that is consistent with the discretisation of the surrounding continuum, ensuring compatibility between the continuous and discrete parts. This, in itself, is again a multiscale problem. To keep computational times acceptable, algorithms are being developed that possess a high degree of efficiency. Related to the research theme “Computational and Experimental Mechanics”.

7.1 Scientific Computing

The main emphasis in this programme is on analysis and numerical simulation of problems arising in technology. Research is often induced by specific applications, yet being seen as part of a larger area where mathematical tools and in particular numerical methods can be applied. Hence both fundamental (numerical) research and applying the results to specific applications are typical for Scientific Computing. The following areas specify the actual research:

7.1.1 Glass Morphology Analysis and simulation of the glass flow in (partially) confined areas, such as in mould for producing jars and bottles. Flows in a glass tank (oven). Investigating the heat transport by various phenomena, like diffusion and convection. Co-operation in this research is with TNO-TPD ceramics and glass. The research is embedded in an EU project “MAGICAL” Furthermore there exists cooperation with the departments of Mechanical Engineering and Chemistry (TU/e). Related to research themes “Computational Mechanics” and “Mechanics of Materials”.

7.1.2 Ordinary Differential Equations and DAE

Problems that exhibit an evolutionary character will result in ODE after spatial discretisation. Moreover problems in control and mechanics often lead to such equations more directly. Quite often they are coupled with some (algebraic) constraint equations, resulting in DAE. Matters like stability and accuracy of numerical methods still provide for important questions. Co-operation exists with the TU/e-department of Mechanical Engineering. Related to research theme “Computational Mechanics”.

7.1.3 Large Scale System Solving

In solving partial differential equations numerically, one encounters complex larger (non) linear systems which exhibit a sparsity structure. In order to be able to solve them one need special iterative solvers, like multigrid. In this area one can also often employ parallel architectures fruitfully. Co-operation exists with TNO-TPD and the TU/e-department of Computer Science. Related to research theme “Computational Mechanics”.

65

7.1.4 Modelling and Finite Element Applications

Although there exists a variety of FEM packages, it is often necessary to tailor methods for specific problems. Further development and improving them is a core activity. A particular aspect is the visualisation, which is increasingly important due to the ever increasing complexity of problems to be solved. Related to research theme “Computational Mechanics”.

7.1.5 Boundary Element Methods and Approximation

The research on BEM is concentrating on the quality of approximations of non-homogeneous problems. In particular it is investigated how various basic approximation methods like radial basis functions lead to convergence and therefore efficient methods. Related to research theme “Computational Mechanics”.

7.1.6 Wave Analysis for lithography Analysis of diffraction gratings that are used to determine the position of a wafer in a waferstepper. Numerical methods like RCWA (Rigorous Coupled-Wave Analysis) are investigated to solve these equations in a stable and accurate way. New software tools will be developed for sensors that have the improved RCWA algorithm incorporated.

Related to research theme “Computational Mechanics”. 7.2 Applied Analysis

The main emphasis in this programme is on mathematical analysis of technological problems. Research is often fostered by specific applications, after which it may trigger more fundamental, and thus more generally applicable research:

7.2.1 Mathematical Methods in Continuum Physics

Slow viscous flow of polymeric melts: considered is the mathematical simulation of manufacturing processes for polymers such as fiber spinning, extrusion and injection moulding. These processes are considered as slow viscous (Stokes-) flows. The polymeric melts are described as nonlinear thermoviscoelastic fluids. Analytical and numerical evaluation of the resulting system of partial differential equations is looked for.

Modelling of direct imaging processing in photocopiers: Description of the toner particles between drum and dip roller, including collision, friction, and electromagnetic forces. Modelling of the toner as a granular medium or as a conglomerate of many rigid particles. Numerical simulation on basis of discrete element analysis.

7.2.2 Fundamental Analysis of (Non-Linear) Evolution Problems Our research in functional analysis is concentrated on evolution equations. An inspiring source of inspiration are non-linear evolution equations arising from free boundary value problems in quasi-stationary fluid dynamics (Stokes flow, Hele-Shaw flow, polymer flow).

7.2.3 Mathematical Methods for Impacting Oscillators In this subprogramme the dynamics of oscillating systems with impacts is studied. These systems

show universal bifurcation behaviour, such as ‘period-adding’ bifurcations. Applications of the theory are found in atomic force microscopy, an experimental method to scan the detailed structure of surfaces from interactions between the surface and an oscillating problem.

7.2.4 Stability of thin-walled structures

66

A variational criterion for the hurt of stability of thin-walled shell structures provides a new lower bound for the loading capacity. We are investigating the implications of this criterion for the classical case of an axially loaded cylinder.

7.2.5 Industrial Mathematics

Problems and questions from industry. All subprogrammes within 7.2 are related to research theme “Mechanics of Materials”.

7. Short description of sub programmes related to research school EM 7.1 Composite Materials

Research within the group is primarily directed to developing damage-based models for predicting delamination and matrix-cracking, particularly for fibre-metal laminates such as Glare. These are being applied to the prediction of fatigue durability and thermal behaviour, as well as the analysis of crack stoppers, splices and combined buckling/delamination phenomena.

Related to the research theme “Computational and Experimental Mechanics”.

7.2 Advanced Computational Procedures This sub-programme relates to the development of computational models for the simulation of the behaviour of materials and structures. For this purpose accurate and robust models are made for the temporal and spatial discretization and algorithms are constructed for the efficient, accurate and robust solution of the ensuing non-linear algebraic equations. Another main thrust is the development of advanced computational mechanics strategies for stochastic phenomena.

Related to the research theme “Computational and Experimental Mechanics”.

7.3 Advanced Materials The research of the group in this area is focused on (i) a better understanding of the underlying

physics of coating systems under ambient and elevated temperatures, (ii) the numerical simulation of phase transformations and dislocation movement and the development of efficient numerical techniques to generate the microstructures, and (iii) the development of robust methods for simulating crack growth in heterogeneous materials and under dynamic loading conditions.

7. Short description of subprogrammes related to research school EM 7.1 Structural Tailoring, and Design and Optimization

The demands of high-performance, structural integrity, durability, low weight, and minimum cost pose an important challenge to structural designers. New materials may assist in satisfying some of these demands, but at the same time give rise to significant new problems for the designers. Furthermore the structural design can no longer be seen as an isolated activity, but must play its part in a multi-disciplinary approach to the design of the aircraft or spacecraft as a whole. The traditional approach to design is no longer adequate unless it can be supplemented by a numerical, computer-based approach in which the trade-off between conflicting design requirements can be quantified, and many more alternatives evaluated. Optimization plays an important role in this process, by providing a tool to identify the active design constraints and to steer the design towards some required goal such as minimum weight or cost. The goal of the research efforts in this area is the development of efficient and robust design and optimization tools for a variety of challenging structural design problems, which meet the needs that industry is facing. The subprogramme includes the following topics:

82

Development of design and optimisation procedures for specific structural design problems; Theoretical optimisation including multi-level procedures and optimisation of structural shape

and layout; Tailoring of advanced fibre reinforced composite structures; Design and optimisation of actively sensed and actuated structures.

Related to the research themes “Reliability and Optimization” and “Computational and Experimental Mechanics”.

7.2 Stability and Vibrations of Imperfect Composite Shells In modern designs, which are often obtained by use of one of the structural optimization codes and which may be of new high strength materials such as advanced composites, structural response is often dictated by the stability and vibration behaviour. This is due to the drive for achieving light weight structures which result in thin-walled constructions. Such structures are also imperfection sensitive and display nonlinear response characteristics. This implies the need to investigate and understand the response characteristics of thin-walled structures under different loading conditions by carrying out extensive numerical calculation and/or experimental verification. A key issue is the development of fast and accurate analysis capability for thin-walled structures, incorporating all the theoretical knowledge accumulated in the last decades through intensive research in the aerospace, nuclear, and offshore fields, and making efficient use of the currently available interactive and (super-) computing facilities. Part of the ongoing thin-walled structures research is therefore concerned with the buckling, post-buckling, vibration and dynamic stability behaviour of shells. The goal of the research efforts in this area is the availability of improved design criteria and the necessary analysis tools. The subprogramme includes the following topics: Theoretical, numerical, and experimental studies of the collapse behaviour and nonlinear

vibration behavior of imperfect composite shells under static and dynamic loading; Development of an International Imperfection Data Bank and DISDECO (Delft Interactive Shell

DEsign COde); Development of efficient semi-analytical and Finite Element based tools (reduced-basis

methods) for the nonlinear static and dynamic analysis of slender and thin- walled structures. Related to the research themes “Computational and Experimental Mechanics” and “Reliability and Optimization”.

7.1 Structural Optimization and Computational Mechanics

Analytical modelling is only possible for a very limited number of structures or parts of structures. With the development of high-performance computer facilities, however, an increasing number of mechanical problems can be modelled and analysed numerically. The finite element method is the method that is often made use of in these cases. Analysis on the basis of numerical techniques is complicated by nonlinearities, caused by material behaviour, geometric effects, contact and/or friction. Moreover, multidisciplinary interaction may be important. This is especially the case for Micro-Electrical-Mechanical Systems (MEMS) and high-tech applications. Because of these aspects, the analysis of practical problems takes a tremendous effort. Therefore, further development of efficient, multidisciplinary numerical modelling techniques is required. These techniques should be tailored for high-performance computer architectures. The aim is to develop such techniques using approaches that strengthen and exploit the fundamentals of engineering mechanics. Once numerical techniques are incorporated in a design process, for which often many intermediate designs and corresponding design sensitivities must be evaluated, the efficiency requirements are even more demanding. This holds for a design process in which intermediate designs are evaluated "manually", but becomes more important for (partially) automated optimization processes. Improvement of structural optimization techniques cannot be achieved independently from new developments in Computational Mechanics. Only a close integration of structural optimization techniques and numerical analysis strategies can yield the most efficient design tools. Clearly, manufacturing constraints impose additional challenges on the optimization. Within this theme, the fundamentals for modelling, analysis, design sensitivities and optimization of structures will be developed. The focus will be on the multidisciplinary links between these aspects. Furthermore, new developments will be translated in prototype designs, ready for laboratory testing and ultimately made available for day-to-day practice. For this purpose we are collaborating with more application-oriented groups and companies. Related to the research theme “Computational and Experimental Mechanics”

7.2 Mechanics of Materials & Microsystems Reliability

94

Demands on functionality and reliability of mechanical products, processes and systems and the needs for continuing improvement of product and process quality are of major concern for the worldwide industry. Traditional experience based design approaches, i.e. trial & error methods (designing, production and testing of a multiplicity of prototypes) can no longer be considered as competitive. Therefore, there is an urgent need to develop innovative design methods. As one of the promising alternatives for the traditional design method, virtual (= simulation-based) prototyping is beginning to draw attention from both industries and the academic world. Adequate virtual prototyping involves a variety of aspects such as mathematical modeling, numerical simulation, functionality and reliability judgement, appropriate optimization tools and adequate experimental verification techniques. Presently, various modeling, simulation and optimization abilities have become available through continuing research and developments in physics, mathematics and engineering. Extension and improvement of these abilities and understanding of the underlying physics have been subject of research and development of many Engineering Mechanics programs. By virtue of the continuing developments in microelectronics and consequently continuing improvement of computational capabilities, an increasing number of mechanical problems can now be modeled and analyzed numerically. Therefore application of virtual prototyping is becoming an increasingly realistic possibility for future design of mechanical products, processes and systems. One of the important building blocks in the process of virtual prototyping concerns "reliable and efficient (mostly FEM-based) mechanical modeling". Within this building block some bottlenecks (or challenges) are presently remaining, while new ones are emerging, despite the tremendous research effort worldwide. Those bottlenecks are mainly driven by the increasing demands on product complexity (application of new complex materials, continuing miniaturization, function integration), reliability and short-time-to-market demands. Examples of identified bottlenecks are:

Characterization and modeling methodologies for process and geometric dependent material properties for various materials.

Damage (and damage evolution) modeling (models & criteria) for various materials.

Reliable experimental techniques for (material-) model parameter identification.

Reliable experimental methods for FEM-model verification. The orientation of the recent (and near future) “Mechanics of Materials” research projects is mainly directed to the elimination of the above bottlenecks and thus to improvement of the “virtual prototyping” chain. The necessary research requires combined experimental and numerical mechanics methods. The understanding and subsequent modeling of materials behavior requires the study and description of physical phenomena, ranging from macro to micro scales. As a main research area with both rich scientific challenges and important industrial interest and application, Microsystems Reliability has been chosen. Reliability is the probability that a product in operation will survive under certain conditions during a certain period in time. Failure is the probability that a product is not functioning as designed. Moore’s law and More than Moore drive micro/nanoelectronics into an unknown level of complexity, characterized by miniaturization down to nano scale, multi and heterogeneous functionality, multi-discipline, multi-scale (in both geometry and time), multi-process, multi-technology, multi-variability, multi-material and interface, multi-damage and failure modes. These technology development trends, in combination with business trends, lead to increased design complexity, dramatically decreased design margins, increased chances and consequences of failures, decreased product development and qualification times, increased difficulties to meet quality, robustness and reliability requirements. As the consequence, product field failure rates and qualification effort are unacceptably high and yield is low, leading to very high cost of non-quality. Industries are losing billions in potential profits because of the field failures and delays in product development, due to

95

many unsolved challenges covering design methods, reliability practices, tools, standardization protocols, and especially the underlying fundamental knowledge. Industries have no appropriate

Designing methods. The currently used ones are o Experience and trial-error based o Empirical, phenomenological and case dependent o Sub-optimization with limited capability for integrated co-design o Associated with high development costs

Reliability qualification methods. The currently used ones are o Time and money consuming o Unclear correlation between application profiles with specifications and between

application profiles with accelerated testing o No guarantee for extrapolating to outside of the specifications o No satisfied coverage for quality, robustness and reliability

To meet the development needs of micro/nanoelectronics, knowledge-based new reliability paradigm is a must. The scientific successes of many micro/nano-related technology development cannot lead to a business success without innovation & breakthroughs in the way that we address reliability through the whole value chain. As an active player in the worldwide micro/nano reliability arena, and one of the founding members for EUCEMAN (European Center for Micro and Nanoreliability), our research focus is to develop fundamental knowledge, methodologies and advanced industry practices that enable industries to predict, qualify, design and optimise the reliability of micro/nano process and products upfront, prior to major manufacturing investments, physical prototyping and qualification tests. Our research scopes cover

Multi-scale (from MD to continuous), multi-physics and multi-parameter based material/process/product characterization and modeling

Damage, reliability and failure prediction and modeling, covering failure modes such as cracks, delamination, fatigue, moisture, degradation, buckling, warpage, various types of migrations, plastic yielding, etc.

Virtual design prototyping/optimization/design rules, and virtual reliability qualification

Advanced failure analysis, test strategy/methods and accelerated reliability qualification tests. Related to the research theme “Computational and Experimental Mechanics”

7.3 Dynamic Behaviour of Mechanical Systems

Predicting and controlling the dynamical behavior of systems has become more important than ever before since new material and design tehniques render structures lighter, more complex, more flexible and multi-functional.Thus predicting their dynamic performance with accuracy is crucial (e.g. response of constructions to surrounding perturbations, positioning of flexible manipulators, dynamic load analysis on machines,.). Also the advent of new materials such as piezoelectric ceramics and the development of novel mechanical structures such as Micro-Electro-Mechanical systems (MEMS) require modern dynamic analysis to take into account the coupling between different physical fields, treated separately in earlier days. Tackling multi-physical problems and analyzing fully coupled systems (thermal, acoustic, electric, fluid and structural for instance) is one of the essential challenges underlying the development of new analysis tools and innovative design approaches in mechanical dynamics. The objective of the research work in the Engineering Dynamics group is on one hand to develop numerical tools that allow analysis of complex systems, and on the other hand to improve the understanding of dynamical behavior (e.g. vibration analysis and measurement, stability prediction). The research is centered on the development of novel numerical methods and

advanced algorithms for efficient computing and testing. Specifically, the section is centering its reseach around the fields of expertise

Multibody Dynamics,

Numerical methods for dynamics,

Multiphysical modeling

Experimental Dynamics and application fields usually considered are bio-medical, automotive, aerospace and aeronautics and Microsystems. Related to the research theme “Structural Dynamics” and also “Computational and Experimental Mechanics”

7.4 Reliability of Structures and Processing

Even the most sophisticated analysis and design procedures traditionally use a deterministic approach, often based on (arbitrary) safety factors. A new dimension is introduced by taking into account the variability in material properties, geometry and operation conditions and to quantify it by means of probabilistic descriptions. The recent ability to operate inexpensive PCs in a parallel network and the development of specific algorithms for computational stochastic methods in a mutiscale context, often with the added complication of non-linearities and multiphysics, have brought within reach a systematic incorporation of the probabilistic aspects in the modelling of engineering materials and systems. A direct consequence of this is the possibility of predicting the reliability of an object or system with respect to a performance requirement in a rational fashion. These advances also have relevance for many problems in processing, where a proper modelling of manufacturing introduced defects is a conditio sine qua non for a proper design of a system. Related to the research theme “Reliability and Optimization”.

7.1 Structural Dynamics and Acoustics (Prof.dr.ir. A. de Boer)

The research in this discipline is directed towards: · Fluid-structure interaction and acoustics, with emphasis on thermal viscous wave

propagation and acousto-elastic coupling and the accompanying noise production. · Structural dynamics, involving rotating components in machinery and optimisation and

actuation of vibrating structures. · Material behaviour under dynamic loading, covering condition monitoring based on

vibration based methods, impact behaviour and rubber modelling. The research of the group aims at generation of new, fundamental knowledge by combining numerical and experimental techniques. Based on this knowledge engineering tools are validated and made ready for application in key industrial problems. A characteristic feature of all themes is the innovative use of advanced numerical simulation methods in a design environment. Crucial

120

information that is difficult or even impossible to obtain from experiments is added through numerical models. Current topics are:

Structural Dynamics (1) Optimization of Dynamic Systems

Optimization problems concerning complex structures with many design variables may entail an unacceptable computational cost. This problem can be reduced considerably with a multi-level approach; a structure consisting of several components is optimized as a whole (global) as well as on component level. Optimizing the dynamic behaviour of a structure in this way gives an extra complication because the interaction loads for each of the components are frequency dependent. The objective of the research is to develop robust and fast methods to address this kind of dynamic problems for large complex structures using neural networks and genetic algorithms in combination with component mode synthesis and making use of repetitive patterns in the structure. The research in 2009 has been focussed on re-analysis methods for reduction methods. This research will be the subject of the PhD-thesis of Didem Akçay Perdahcioğlu which will be defended on July the 9th , 2010. A new project has been started on the optimization of thermoplastic structures in the framework of the Dutch TAPAS (Thermoplastic Affordable Primary Aircraft Structure) programme. The research of the UT part within TAPAS will be the subject of the PhD-thesis of Samuele De Guido.

(2) Rotor Dynamics Rotating parts in machinery are sources of vibrations and can therefore affect the life time of the rotating part itself and the whole machine drastically. The tendency to optimize the functional performance of structures results in modern designs which often exhibit a minimal weight and very tight safety factors. For high speed rotating micro systems, a well-known rule is that with decreasing scale, surface effects begin to dominate volume effects. This means that friction (e.g. in the support system of the rotors), aerodynamic damping, thermal effects become very important and have to be taken into account in the models. Therefore the type of models used will be typical for the multi-field microsystems setting. A model has been developed to calculate the aerodynamic loads in the containment between rotor and housing and coupled with the rotor dynamics and thermal model. Further an experimental set-up has been designed and built to validate the developed multiphysics model. This research is the subject of the PhD-thesis of Emre Dikmen. In 2009 a separate project has been carried out with the objective to develop identification methods for special bearings in the support system of high speed rotor systems. This research was carried out by post-doc Vikas Arora.

Fluid-structure interaction and acoustics

(1) Viscothermal wave propagation New, analytical models, which include the effects of inertia, viscosity and thermal conductivity, led to the development of a new finite element for viscothermal wave propagation in narrow gaps. Coupling of this acoustic element with finite elements for the structure enables fully coupled acousto-elastic calculations for a complex geometry to be made. The models were validated with specially designed experiments. The enormous effect that the presence of air can have on the vibration behaviour of a structure was shown and it appeared possible to generate a considerable amount of damping. In 2009 the computation speed of the viscothermal finite elements has been increased drastically and validation

121

experiments have been carried out. This research will be the subject of the PhD-thesis of Ronald Kampinga which will be defended on June the 23rd 2010. Further studies are performed towards practical applications more specifically for computers. 2D and 3D finite elements have been developed which make it possible to apply the viscothermal wave propagation theory for arbitrary geometries. This research will be the subject of the PhD-thesis of Martin Nijhof.

(2) Sound-absorbing materials.

A closely related part of the research program, involves the development of methods and models concerning sound-absorbing materials. In 2009 emphasis is put on a new method of measuring the absorption of materials in-situ. This research is carried out by Erwin Kuipers.

(3) Efficient analysis and measuring methods for source localisation Acoustic source localisation concerns a combination of measuring and numerical analysis methods with the goal to detect the parts of a structure that are responsible for the generation of noise. The idea is to measure the sound pressure or particle velocity on a grid around the radiating object and to determine the radiating source with inverse analysis methods. In 2005 the STW project TWO 5154 “Efficiente akoestische reken- en meet-technieken” was finished and the new STW project TWO 6618 “Inverse Akoestiek” was started. This project is carried out together with Prof. Slump of the UT Department of Electrical Engineering, Signals and Systems group and Prof. N.B. Roozen of the TU/e Department of Mechanical Engineering, Section Dynamics and Control. The goal of this project is to develop fast methods to localize noise sources with acoustic sensor arrays. In 2009 a method to localize moving noise sources has been investigated and developed. This research was the subject of the PhD-thesis of Jelmer Wind which was defended on November the 18th , 2009.

(4) Thermo-acoustic structural interaction

During combustion in a gasturbine noise is generated which can interact with the gasturbine wall. Due to this interaction undesirable acoustic pressure fields can be generated that disturb the flame. The latter can affect the efficiency of the combustion process. The objective of this study is to investigate the interaction between the gasturbine structure and the thermo-acoustic pressure generated in the combustion chamber. This study is carried out in close collaboration with the Thermal Mechanics group of the University of Twente. In 2009 a new (Marie Curie) project focussed on fatigue of the liners has been started on this subject. This research is carried out by Can Altunlu.

(5) Tyre/road noise Traffic road noise is a serious environmental problem and effective countermeasures are needed to reduce noise. The main components of the radiated noise are engine noise and tyre/road noise, where engine noise dominates at low speeds. Road noise is generated through the interaction between a rolling tyre of a vehicle and the road surface. Many different mechanisms contribute to the generation of tyre/road noise. Because most generation mechanisms originate from the contact region, modelling of the interaction between tyre tread and road surface is crucial for an accurate prediction of tyre/road noise. With such a complete model, one can study the effect of modifications to the tyre or road, and ultimately design quieter tyre/road combinations. The objective is to develop numerical tyre/road models with emphasis on what is happening in the contact region and the material models for rubber. In 2009 an analysis procedure has been developed such that the radiated tyre noise can be calculated. This research will be the subject of the PhD-thesis of Arjan Schutte.

Dynamic material behavior

(1) Structural Health Monitoring This project is in collaboration with Production Technology, Prof.dr.ir. R. Akkerman. See chapter 13 ‘Production Technology’ for more details.

(2) TTIW Wetsus Distribution. The research program of the Technological Top Institute Water, financed by the Dutch government and Dutch industry, covers a wide range of projects, amongst which the remaining life time assessment of water distribution pipes. Premature failure can result in high maintenance costs and public inconveniences, whereas premature replacement of large parts of the water distribution network is logistically impossible and extremely costly. Previous researches on PVC gas pipes revealed the effect of physical aging on the type of failure. Moreover, the dynamics of the ground in which the pipes are embedded can cause extreme deformations and depending on the level physical aging to damage. Ultrasonic measuring technologies are being developed (see InnoWator project) to measure the dynamic response of a water pipe during service. The relation between the dynamic response, the age of the material and the resulting remaining life time estimation are subject of the Wetsus theme program Distribution. The current focus is on PVC material. Complicating factors involve the unknown initial material properties, such as the level of gelation, and non-linearities in the (dynamic) material properties. Artificial rejuvination and aging are employed to investigate the physical aging kinetics and their relation to physical material properties. Beginning 2010, Mahmoud Ravanan started his PhD research on this project.

(3) InnoWator This project is in collaboration with Production Technology, Prof.dr.ir. R. Akkerman. See chapter 13 ‘Production Technology’ for more details.

(4) Rotor Blade Dynamics Green Rotor Craft (GRC) is one of the research projects whitin the European funded Joint Technology Initiative research program “Clean Sky”. The objective of the GRC project is to reduce the environmental impact of helicopters. A smart use of resources, in terms of vibrations of the rotary system, and an optimisation of the rotor blade performance are set as the main research activities. Two PhD position are defined in this project. The first part of the research is focussed on power harvesting methods. The energy of vibrations in the rotor’s lag damper and of the rotorblade itself can be extracted by employing for example piezo patches. Design and development of the electrical circuits in order to maximise the power output from a complex dynamic system such as a rotor blade is a challenging and relatively unexplored problem. February 2009, Pieter de Jong started his PhD research on this project. First activities involved an study on the available power harvesting methods and circuits, which are collected in a Initial Technology Review. The review is assessed by the GRC project task leader (Agusta Westland) in December and is issued as a deliverable in January 2010. The first results will also be presented at ICSV-17 (July 2010). The second part involves smart shaping of the blade in order to optimise the performance during different flight conditions. The main interest is the development of a suitable activator principle and design for a model rotor blade. The dynamic loading on the blade, which varies during advancing and retreating motion of the blade is a complicating factor. The demands on the actuator performance and the coupling between actuation of a shape morphing mechanism and the rotor blade dynamics require a fundamental understanding of actuator behaviour. Additional challenges are found in the scale of the model rotor and the impossibility to either upscale or downscale solution from model rotor to a full scale blade and vice versa. Generic solution technology need to be developed to bridge this gap, resulting in a robust full scale smart blade design. February 2009, Alexandre Paternoster started as a PhD on this project. A technology review, assessed by the GRC project task leader (Agusta

123

Westland), was finished in December (issued in January 2010 as a deliverable). It incorporates an extensive overview of available technologies and a new selection methodology based on a comparison of work per weight versus actuation time rather than force versus displacement.

7.2 Mechanics of forming processes (Prof.dr.ir. J. Huétink)

The research in this discipline is directed towards the development and validation of numerical methods to simulate forming and production processes. Industrial application of numerical simulations of forming processes is gradually finding its way in industry. For specific forming processes commercially available software packages can provide predictive answers. There is a strong need for more accurate macroscopically based descriptions of material behaviour during specific parts of the forming process, more accurate descriptions of the process conditions such as friction and heat transfer between tools and workpiece and above all, experimental verification of the capability of the models to describe the phenomena with sufficient accuracy. The fundamental problems associated with new algorithms, the inclusion of relevant boundary conditions like contact and friction between tool and product, and the deformation of flexible tools are addressed. These fundamental problems obviously occur in very important technologies that have attracted (renewed) attention in recent years. The sub programme is to a large extent part of the Research programme of the Materials Innovation Institute (M2i) (previously NIMR). Several research projects are joint activities of the UT, TU/e and TUD Increased demands for accuracy of these simulations and computationally efficient simulations require that a number of topics have to be addressed:

Improved macroscopic models for describing the material. Accurate constitutive equations are required including (evolution of) sheet metal anisotropy in order to predict the final shape after forming and subsequent “spring back”. In particular the effect of the initial sheet anisotropy, the changes in loading path as present in multi-stage forming processes and through process modelling, the strain rate dependency, the consequences of temperature changes in warm forming processes, the effects of annealing periods between successive forming steps and strain rate effects have to be properly accounted for. Material properties are commonly determined from uni-axial and/or proportional deformation test. In forming processes the stress state is not uniaxial, and the deformation path is not proportional. In order to develop and validate material models under multiaxial stress state and arbitrary deformation paths, a biaxial test facilty is developed. The test facility allows for biaxial loading under simultaneous bi-directional shear and tension/compression of sheet metal, including strain path changes and strain rate changes. In the project on strain path dependent material models this equipment is further developed and the results are used to validate and to improve macroscopic material models (PhD researcher Maarten van Riel). The Project “Simulation of thermo-mechanical forming of aluminium sheet” addresses both the material hardening aspects during warm forming and the effect of annealing periods (PhD researcher Srihari Kurukuri). The project is jointly executed with TUDelft. With the TU/e and TUDelft a joint FOM-NIMR project "Tailoring of processable metastable steels" is running. The project has resulted into constitutive equations for FEM simulations, including the phase transitions from austenite to martensite during forming. At the TU/e micro level FEM models are developed that can foster the development of the macroscopic models that are necessary in full-scale three dimensional forming process simulations. PhD researcher Semih Perdahcioğlu has defended his thesis December 2008, has continued his work in a valorisation project in

124

cooperation with Philips and started as a post-doc on a project ”Mechanically induces martensite in stainless steel and Trip steel”. The project “Plasticity in stainless steel and TRIP steels at non proportional strain paths” aims to continue the development of a general (constitutive) deformation model to describe the behaviour of single and dual phase steels with or without phase (austenite to martensite) transformations. The deformation model should be able to describe the effects of texture and phase transformation during forming operations. The model will be an extension of the ‘stress induced transformation’ model (PhD researcher Peter Hilkhuijsen). The project “Forming the Limits of Damage Predictions – From fundamentals to application” is also a joint activity of the TU/e ant UT. The aim is to develop computational tools which allow one to make quantitative predictions of ductile damage and fracture in industrially relevant materials and applications (researcher Harm Wisselink). A project on anisotropic damage has been started in 2007 (PhD researcher Muhammad Sohail Niazi). The effect of bending on the formability limits is studies in a two years post doc project (researcher Alejandro Martinez Lopez).

Optimisation Superplastic forming of aluminium foils is investigated and the optimisation towards constant final thickness considered (PhD researcher Corijn Snippe). The optimisation is geometrically based rather than process based, since the overall costs of the foil product will be the result from development time and not from the chosen material or production process (low mass production). In the project on ‘Lubricant free piston compressor’ the thermo-mechanical conditions, especially in the start-up phase for a free piston compressor are optimised. Small tolerances and thermal expansion are the main topics here (PhD researcher Pawel Owczarek). In 2009 a project is started on “Design of robust forming processes”, (PhD researcher Jan-Harmen Wiebenga).

Advanced solution algorithms for forming processes In the project ‘modelling of incremental sheet forming’ the focus is on efficient modelling techniques for a process in which only a very small part of the work piece experiences plastic deformation at a particular time. Considered methods are refinement and de-refinement and sequential (dynamic) substructuring (PhD researcher Ashraf Hadoush). This research is carried out in cooperation with RWTH Aachen. In addition continued research will be performed on dynamic-implicit algorithms in combination with direct and iterative solvers. For aluminium extrusion, full 3D simulations of the bearing area are still very time consuming. Equivalent bearing areas and improved steady state simulations are investigated by Bert Koopman and Wissam Assaad. A project on the applicability of meshless methods for forming process simulations is started in 2007 (PhD researcher Wouter Quak).

Joining, surfaces, contact and friction, The project “Local Alloying and Cladding of Advanced Al-Alloys Employing Friction Stir Welding” is aimed to develop an innovative modified tool for the Friction Stir Welding (FSW) process. Contrary to regular FSW, filler material is supplied to the weld area during welding through an adapted FSW tool. This is a joint project with the production Technology group (PhD researcher Arnoud van der Stelt). A project jointly with the Surface Technology group is “Friction modelling in sheet metal forming on multiple scales”. The aim of the project is to provide a friction model that describes the effects

125

of the surface topology on the micro scale in FE simulations on the macro scale. The algorithm incorporating the model must be applicable to full-scale automotive sheet metal forming simulations (PhD researcher Johan Hol). All activities within the sub programme “Mechanics of Forming Processes” are related to the research theme “Computational and Experimental Mechanics”.

The subject of research of the surface technology and tribology group is the interaction of surfaces and engineering practices related thereto. The nature of the interaction between the opposing surfaces depends on the operational conditions. Therefore: different lubrication regimes are distinguished: A) full film lubrication, mixed lubrication and boundary lubrication and B) unlubricated or dry contact. The physics describing the interaction is quite different. Since in most mechanical engineering applications all regimes are encountered, research is conducted in all these areas, with special attention for the transitions between regimes with respect to friction and wear. Based on modelling design tools are developedfor reliable and accurate prediction of tribological behaviour in practical applications. The main subjects are I) Lubricated systems, II) Materials and Coatings and III) Skin-Tribology. In 2009 A new topic is initiated: Tribology Based Maintenance.

7.1 Tribology

The research conducted in this subprogramme deals with the frictional behaviour in lubricated contacts. The local interaction between the opposing surfaces is studied by developing elastic-plastic contact models. On the basis of the models developed Stribeck curves can be predicted for lubricated contacts. With these models one is able, in combination with the critical contact temperature hypothesis, to predict the load carrying capacity of lubricated systems. Also with this model the influence of wear (a few micrometer wear depth) on friction in lubricated concentrated contacts can be predicted. For systems set in motion or set still friction is determining the position of a system. Within this subprogram attention is paid to single and multi-asperity contact. Related to research theme: “Computational and Experimental Mechanics”.

7.2. Surface technology and Surface Roughness

Surface roughness has a significant influence on the tribological behaviour (friction and wear) of a system. Therefore, the prediction of the change in roughness, running-in, as a function of the operational conditions is one of the topics which is under investigation by the surface technology

133

and tribology group. A deformation model is developed for the contact between a rolling hard spherical body in contact with a rough soft surface. On the basis of this model one can determine what the initial roughness should be to generate a certain roughness level during operation. This model will be extended for a rolling/sliding ball on a flat situation. In certain applications the surface roughness should not change too much in order to maintain a certain friction level. This change in roughness is the result of local deformation and the wear mechanism involved. For certain applications, as for instance in sheet metal forming, transfer of sheet material to the tool changes the micro-geometry of the tool significantly and as a result friction changes during operation.

Related to research themes: “Computational and Experimental Mechanics” and “Reliability and Optimization”.

7.3 Materials

The research focuses on the development of self healing nano-scale oxide ceramic (alumina, zirconia and their composites) couples with low friction by adding metal oxides to the ceramics during material processing. A thin interfacial layer forms between the opposing surfaces during rubbing. The mechanism of the interfacial layer formation is studied in order to optimize the ceramic material with respect to self healing.

In sheet metal forming processes the type of lubricant and coatings are becoming more and more important. The modeling with respect to friction and wear focuses on local ploughing, cutting and wedge formation. Wear is experimentally studied with a surface force apparatus and will be compared with the model. The galling phenomenon is studied for the aluminium extrusion and hydrostatic magnesium extrusion process. For the latter process the influence of the fluid is studied extensively. Related to research themes “Computational and Experimental Mechanics” and “Reliability and Optimization”.

7.4 Experimental Validation Different friction and wear models are developed which are validated by experiments. For certain

processes, as for instance cold rolling, models are available which are not validated by experiments yet. In this research measurement techniques will be developed to measure friction and wear under specific operational conditions. Attention is for instance paid to measure 1) semi on line micro-wear by using a tribotester connected to an interference microscope and 2) friction in wheel rail contact. Next, measurement techniques are developed to measure the material transfer of the sheet to the tool by using interference microscopy and a surface force apparatus. Further, research takes place with respect to the tribological behaviour of materials in systems operating under cryogenic circumstances. A cryogenic tribotester is build for this purpose as well as a high vacuum single asperity tribotester. Related to research themes “Computational and Experimental Mechanics” and “Reliability and Optimization”.

7.5 Bio-Tribology Research is started on the topic “skin - object interaction”. To design a product based on comfort,

in which contact takes place between skin and product like artificial grass or a shaver, the designer has no “tools”. In this research a design comfort diagram will be developed based on a thermal-, mechanical- and skin parameter. As a start a non-isotropic visco-elastic elastic contact model as well as a portable friction device is developed. Related to research theme “Computational and Experimental Mechanics”.

The research topics of the group Mechanical Automation related to the speciality of Engineering Mechanics can be summarised as:

139

7.1 Robotics and Micro Mechatronic Systems The dynamic behaviour of (industrial) robots and (micro) mechatronic systems is investigated. For analyses and efficient simulations the computer program “SPACAR” has been developed. It is based on a non-linear finite element method to analyse and simulate the kinematics and dynamics of mechanisms and manipulators or, more generally, multibody systems with non-linear behaviour due to large displacements and/or rotations. In this approach mechanisms may be composed of both rigid and flexible components. Locally linearised models can be derived to study e.g. natural frequencies and vibration modes. The low-dimensional models that are obtained in this way appear to be particularly suited to obtain prototype models of the mechanical part of a mechatronic system. For control synthesis of such systems it is essential to make use of simple prototype models with a few degrees of freedom that nevertheless capture the relevant three-dimensional system dynamics. Manipulators in Micro Electro-Mechanical Systems (MEMS) typically make use of elastic members for predictable behaviour as elastic mechanisms are characterised by low hysteresis, zero backlash and no friction. The main goals of the CLEMPS project are the mechatronic design, realisation and validation of a closed loop system with a MEMS device. MEMS are manufactured in a clean room. Therefore the cost of prototyping and the time consumed in the clean room is high compared to ordinary devices. Consequently modelling should be used to reduce the cost and time of making the device. The mechanical structures in MEMS are created in silicon or silicon nitride. These materials allow much larger strains than metals. Therefore relatively large deformation of the elastic members is allowed. The above mentioned finite element approach implemented in the computer program “SPACAR” has proved to be particularly suited for the analysis of (lateral) buckling and stiffness decrease of elastic mechanism members in MEMS. In the MOV-ET project manipulator concepts are investigated to realise high precision motion in vacuum. Our contribution to this project focuses on the use of elastic (or compliant) manipulators. These offer the advantages of motion with low friction and no backlash. However, to realise relatively large strokes, the elastic joints will exhibit non-linear behaviour. In particular the support stiffness decreases significantly which causes a deterioration of the system’s performance. SPACAR models are applied to optimise the design of new joint concepts such that a high support stiffness is combined with a low actuation stiffness in the full operating range and with acceptable stresses in the elastically deformed parts. Furthermore, these models can detect overconstraint or underconstraint system design and offer insight to avoid these conditions. Related to the research theme "Structural Dynamics and Control".

7.2 Vibration isolation control

The tendency towards miniaturization in precision technology leads to a constant decrease in accuracy specifications for precision machines. Disturbances, often produced by vibrations of the floor, machine parts or acoustics, are becoming an increasing problem. In order to cope with future accuracy demands for precision machinery a (better) solution for these vibrations is required. The aim of the research project on “Design of smart mount for application of vibration isolation in precision machinery” is to increase the isolation performance by the application of different concepts of active vibration isolation control and active damping as well as the formulation of design principles for mechanical realizations of mounts. The mounts consist of an active sub-system of actuators, sensors and a control strategy next to the mechanical structure. The active subsystem uses measurements to generate anti-forces in the mount which are opposite to the excitation forces.

140

Control strategies in vibration control have been investigated experimentally with a three dimensional set-up. This set-up consists of a source plate excited by piezo-actuators. Vibrations from the source pass through the three mounts to the receiver frame. Source plate and receiver frame accelerations are measured by 12 accelerometers and 6 actuators produce forces based on the sensor signals that counteract the forces due to vibrations. In this manner the source is isolated from the receiving construction. Next to the described feedforward control strategy a feedback strategy is added to provide damping of the internal modes of the receiver frame. This project will be concluded with a PhD defence in 2010. Related to the research theme "Structural Dynamics and Control".

Research in the Production Technology group addresses the technical issues of new products and new processes. The group focuses on the optimisation of both the manufacturing process and the product performance. ‘Processing’ and ‘Product performance’ of lightweight materials in structural applications characterise the main research themes of the Production Technology group. In our view processing and performance can be optimised after thorough analysis and modelling in combination with a firm experimental programme. The experiments identify the operating mechanisms, establish relevant material property data for the modelling and provide data to test the accuracy of the models proposed. An integral approach is pursued, taking into account the interrelations between the geometric design, the production process and the material properties. In the year 2009, many new research projects were started. Various PhD students started within the EU Clean Sky initiative, developing technologies for greening air transportation: less fuel consumption and less noise. In this year also the ThermoPlastic composite Research Centre TPRC was founded in Twente by Boeing, Stork Fokker, Ten Cate and UT. TPRC aims to advance TPC technology towards automated processing with controlled repeatable product quality, supported by novel CAE tools to include process constraints in the design phase. Two subprogrammes are distinguished: Automated Composites Manufacturing and Performance of Advanced Materials.

7.1 Automated Composites Manufacturing

The first research theme is concerned with the cost-effective application of advanced continuous fibre reinforced composites. The breakthrough of this type of materials in various applications has occurred to a smaller extent than might have been expected, mainly due to their high costs of manufacturing. Thermoplastic composites in particular have the potential to overcome these hurdles.

In general, research in the PT group starts from of a thorough analysis of the deformation and flow mechanisms involved during manufacturing and the modelling of these mechanisms. Design tools are developed to support the production of composite structures with modern techniques.

145

The aim of these design tools is mostly to optimise the process settings in order to obtain a composite component having a prescribed shape or combination of materials properties.

High Precision Composites Moulding Friction in composite forming processes, both between successive composite layers and between the laminate and the tools, was characterised experimentally, as part of a post-doctoral research project. Multiscale models (solving Reynolds’ equation at the meso level) appear to capture the phenomena observed during the experiments. After redesigning the friction test set-up, Dr. ten Thije determined accurate friction data (as a function of pressure, sliding velocity and temperatures up to 400°C), implemented an appropriate model in the FE code and validated the model with press forming experiments. After concluding the project on thermoplastic composite consolidation Ir. W. Grouve continued research on the laser assisted tape placement process within the Clean Sky initiative. Here, the aim is to consolidate the thermoplastic tape ‘in situ’ after rapid local heating by means of fibre lasers. The mechanical behaviour of fibre bundles during textile composite processing is subject of the PhD research by Ir. Cornelissen. The microscale phenomena between the filaments are being investigated in order to predict the mesoscopic behaviour of the bundles during e.g. tension, bending, shear and compaction of technical textiles. Ir. Haanappel started on a project within the TPRC on ‘complex stamp forming’, focussing on press forming of locally reinforced (i.e. tailored) thermoplastic composite blanks, manufactured by a tape placement process. Constitutive models have to be developed for these unidirectionally reinforced materials at forming temperatures, implemented in a robust manner and characterised accurately.

7.2 Performance of Advanced Materials

The second research theme involves a better understanding of the mechanics of new materials, focusing on the physical properties of the component and taking into account the production process used. An increasing range of properties is being considered, from thermomechanical properties such as stiffness and structural integrity, to optical and electromagnetic properties on the short and the long term. Materials with ‘added functionality’ (e.g. composite with integrated sensors and actuators or even self-healing capacity) receive growing interest. The current research projects in this theme are:

long term performance of thermoplastics

active composites

transverse reinforcement of composite materials

long term performance of inkjet printed electronics

friction stir processing of light metals Long term performance of thermoplastics

The PT group investigates the long term performance of non-reinforced pipework. Condition Monitoring in plastic pipe gas distribution networks can assist in ‘smart maintanance’, replacing gas pipes (at the end of their design lifetime) only when necessary. Physical ageing decreases the fracture toughness which can lead to premature failure. The long term performance as measured with pressurised pipe tests can be predicted using models (dr. Govaert, TU/e) fitted with elementary experiments such as tensile and compression testing on specimens of different ages. It was shown that the brittle-to-ductile transition termperature increases with the physical age of PVC. Ir Visser finalised his PhD thesis on this subject before the end of the year. In addition, Dr Demcenko started on ultrasonic methods to determine this physical age, funded via the MEA.

146

Further research on this topic is funded via the TTI Wetsus. Recruiting a PhD student for this position and settling the legeal formalities took considerable time, such that this project could not start before January 2010.

Active Composites Dr. Perdahcioglu continued the post-doctoral research project on self healing thermoplastic composites. A finite element implementation was developed for shape memory alloy wires to simulate the self healing mechanism, combining local clamping and melting while heating and thus re-consolidating delaminated regions in the thermoplastic composite component. Another 2-year post doctoral position was filled by dr Ivanov, working on the use of supramolecular polymers (in co-operation with the group of prof. Sybesma, TU/e). The very low viscosity of these materials can be used to repair composite damage by means of heating and by filling cracks and delaminations. Composite damage may be difficult or impossible to detect visually during regular inspection. Composite materials are, however, well suited to embed strain sensors such as fibre optics. These can in turn be employed to record changes in the dynamic response of composite structures. This information can be used to detect and localise damage, as is investigated and elaborated by ir. Ooijevaar in his Clean Sky funded project on structural health monitoring. In addition to sensing, also actuation mechanisms can be incorporated in composite materials, leading to active light weight structures. This is investigated in the Clean Sky funded project of Paternoster MSc for the application of intelligent helicopter rotor blades. Both Clean Sky projects are conducted in co-operation with the Structural Dynamics and Acoustics group of prof. de Boer.

Transverse reinforcement Carbon nanofibres can be grown on microfibres by means of catalytic deposition. This can be used in composite materials to improve the properties transverse to the fibre orientation. The four research positions within the two participating groups (PT and CPM, prof. Lefferts) were filled in the course of the year. The first efforts were devoted to scale up the CNF deposition process.

Long term performance of inkjet printed electronics Phased Array Communication antenna for Mass-market Application Needs (PACMAN) aims to develop integral low cost implementations of complex technologies developed in defense and astronomy applications. The project is a co-operation with Thales, Astron and the TU/e. Ink jet printing of electronic circuits is seen as a novel cost effective enabling technology in this respect. The PT group concentrates on the mechanical performance of the deposited structures, on both the short and the longer term. Ir. Sridhar’s finalised his thesis in the end of the year.

Friction Stir Processing Friction Stir Welding is a semi-solid forming process, suited for low temperature joining of e.g. aerospace Aluminium alloys. It proves to be possible to extend this process by means of adding an extra material during stir welding. Dr. Christoulis developed a set-up to realize this concept on the FSW equipment installed in the course of the year. Related to this, the PhD project of Ir. Van der Stelt focuses on process modeling in order to achieve better understanding and process optimization.

All activities within the programme are related to the research theme “Computational and Experimental Mechanics”.

This research will be at the junction of three areas: Dynamic unstructured grids and their refinement, hierarchical data structures for coarsening and micro-macro methods, and coupling of various techniques and fields across the scales. The idea is to provide new ways of coupling between particle and continuum methods, for multi-scale modeling, not only relying on a future increase of available computing power, but also keeping massive parallelization in mind. At present, hierarchical hash tables for efficient simulation of poly-disperse systems and FEM/DEM coupling for fluid particle interaction problems e.g. porous media, fluidized beds is being explored.

7.1.2 Computational methods for scale bridging in composite materials

The computational modeling of fracture in composites, concrete, and other cohesive granular materials will be performed and analyzed following a hierarchical multi-scale approach, involving parallelization and tree-data-structures for both the particle analysis and the continuum analysis. A question from the mechanics side is the understanding of the formation of cracks and the ability to predict the conditions (mechanical, environmental) under which they occur or are triggered. Are the small scales more important than the large ones? This makes crack growth (from its initial micro-state up to dimensions leading to failure of a material or a structure) a research issue of paramount importance – and a challenge from the algorithmic and numerical point of view.

7.1.3 Jamming and Creep in Granular Materials

The project is addressed to probe the connections between jamming, creep, shear banding and microstructures in numerical simulations of Brownian and non-Brownian systems with various interaction forces, shear rates, stress regimes at multiple scales.

7.1.4 Computational multi-scale modelling of super-dispersed multiphase flows

The goal of the research is the development of good numerical models for dry granular flow, which is of interest in many industrial processes and geophysics. Granular material shows both solid and fluid behavior. Closed continuous models for granular flow only exist for certain cases, while Discrete Particle Models (DPM) are unfeasible for large-scale simulations. Therefore the work focuses on a DG finite element model for heterogeneous multiscale modelling of polydisperse, nonuniform dry granular flows, which allows both efficient and reliable numerical simulations.

7.2 Instability in multiScale materials

Traditionally instabilities have been viewed as an inconvenience, with research focusing on how to avoid them. Instead they can be exploited to create new materials with improved and

152

switchable properties. Many technological applications, including acoustics, optics and electronics, require the development of new materials with improved and possibly even tunable properties. Particular attention is reserved to materials characterized by a regular micro-structure. Both Nature and technological applications make extensive use of materials to achieve different properties and attributes. Examples are given by phononic/photonic crystals, sensors, super-hydrophobic surfaces and the surface structure of beetles and fishes. We explore the nonlinear microscopic behavior and failure of such materials. This investigation will pave the road to the use of the pattern switch occurring at instability for creating a new class of materials with switchable functionalities.

7.2.1 Instability induced pattern switches in granular crystals

The specific project refers to the investigation of large deformation behavior of two and three-dimensional granular crystals consisting of elastic and rigid particles. The investigation takes the form of numerical and experimental tests, which confirm the existence of global pattern transformation triggered by the applied load. The findings have consequences for the fabrication of tunable granular meta-materials and energy and shock absorbers. The implementation of a continuum model able to describe the evolution of the material structure is a further goal of the project.

7.3 Structural Dynamics and Acoustic (Prof.dr. S. Luding)

In this project sound wave propagation through different types of dry confined granular systems is studied with three-dimensional discrete element simulations, theory and experiments. The influence of several micro-scale properties: friction, dissipation, particle rotation, and contact disorder, on the macro-scale sound wave propagation characteristics are investigated. Experiments, analyzed with the “Spectral Ratio Technique”, make it possible to extract frequency-dependent propagation velocities and attenuation. An improved set-up for future investigations is proposed in order to better understand dispersion and propagation of sound in granular materials. The full dispersion relation of a Face-Centered-Cubic lattice is derived from a theoretical analysis that involves translations, tangential elasticity, and rotations. The additional displacement and rotation modes and the energy conversion between them is studied using discrete element simulations. Simulations and theory are in perfect quantitative agreement for the regular lattices examined. As a first small step away from order, systems with weak geometrical disorder (system structure) but strong contact disorder, i.e. with an inhomogeneous contact force distribution, are studied next. They reveal nicely the dispersive nature of granular materials and show strong frequency filtering. Low frequencies propagate, whereas high frequencies vanish exponentially. A more detailed study of how energy is transfered between different wavenumber bands shows linearly increasing transfer rates for increasing wavenumbers. A first theoretical approach using a linear Master Equation leads to a quantitative prediction of the energy evolution per band for short times. A bigger second step in complexity is made by investigating the sound propagation in a realistic tablet made of a sintered frictional and cohesive polydisperse powder and prepared in different ways. These simulations nicely display history dependence and the effect of different material parameters on sound propagation in particulate solids.

7.4 Mechanics of Forming Processes 7.4.1 Non-Newtonian behavior of granular flows in nano-channels

Highly confined fluid or particle flows typically show strongly non-Newtonian behavior. A channel geometry is often used to study the inhomogeneous behavior of strongly confined fluids. The understanding of these non-Newtonian fluid problems is still very limited, while gaining a deeper insight into these systems is becoming increasingly important with the rise of microfluidic and

153

nanofluidic applications, such as lab-on-a-chip device. Very similar phenomenology (i.e. layering, anisotropy) is observed in many particle systems. The goal of the study is to investigate the non-Newtonian transport properties of granular flows, investigate the effect of wall-fluid interaction, surface roughness and wall-morphology on the material behavior. Molecular dynamics simulations are used to investigate various physical properties.

7.4.2 Size segregation in dense granular avalanche flows

Dense, dry granular avalanches are very efficient at sorting the larger particles towards the free surface of the flow, and finer grains towards the base, through the combined processes of kinetic sieving and squeeze expulsion. This generates an inversely graded particle-size distribution, which is fundamental to a variety of pattern formation mechanisms, as well as subtle size-mobility feedback effects, leading to the formation of coarse-grained lateral levees that create channels in geophysical flows, enhancing their run-out. A continuum model of size segregation for dense granular free surface flows have been developed. A large number of analytical and numerical solutions to these equation have been constructed and compared to experiments. The focus of this research is now on using this model to explain phenomena caused by segregation. These include pattern formation in rotation drums, levee formation in geophysical flows, particle size structure of a flowing finite mass of material in avalanches and axial segregation in long rotating cylinders.

7.4.3 Modeling of Long-range interaction forces and clustering

Clustering in granular material is since long a hard topic. It is a generic and paradigmatic example for the special behavior and [properties of granular matter: long and high densities co-exist, large gradients and shocks occur, both solid and liquid-like behaviors are observed inside the clusters. The objective of the project is to develop a three dimensional Molecular Dynamics (MD) environment and hydrodynamic theory for modeling long-range interaction forces based on hierarchical algorithms, to reproduce clustering of particles.

7.5 Discrete particle self-healing material models

Using an advanced history dependent contact model for DEM simulations, including elasto-plasticity, viscosity, adhesion, and friction, pressure-sintered tablets are formed from primary particles. These tablets are subjected to unconfined uni-axial compression until and beyond failure. For fast and slow deformation we observe ductile-like and brittle softening, respectively. We propose a model for local self-healing that allows damage to heal during loading such that the material strength of the sample increases and failure/softening is delayed to larger strains. Local healing is achieved by increasing the (attractive) contact adhesion forces for those particles involved in a potentially breaking contact. We examine the dependence of the strength of the material on (a) the damage detection sensitivity, (b) the damage detection rate, and (c) the (increased) adhesion between healed contacts. The material strength is enhanced, i.e. the material fails at larger strains and reaches larger maximal stress values, when any of the parameters (a) – (c) is increased. For moderate damage detection sensitivities, the material strength increases with both increasing healing rate and increasing adhesion of the healed contacts. For very large adhesion between the healed contacts

154

an interesting instability with strong (brittle) fluctuations of the healed material’s strength is observed.
