Outline
Part I : Maine points in the model’s geometry :
- Sketch the model
- Different boundary conditions and materials
- The material specific stress and strain values
- Animation of the processes
Part II : View and explanation about the results from
the simulation :
- Viewing and organization of all final results
- Behaviour of the materials in different situation
about material 2
(different values of the applied force)
Part I.I: Sketching
Beam with dimensions 1200x40x100 mm which is
fixed and loaded as is shown in (firg.1).
Beam material is homogeneous bilinear hardening with yield strength 80 MPa and
Poisson’s ratio ν=0.27 (fig. 2).
Assignment’s parameters :
Part I.I: Sketching
Step One
Creating our sketch using cut tools which are on the left site of the window program
Part I.I: Sketching
Step Two
When we finish our sketch we extrude it to create the final look of the wonted picture
Part I.I: Sketching (Special cases)
Case 1 (TREE IN ONE)
Case 2 (INDIVIDUALY ONE BY ONE)
Part I.2: Boundary condition and materials
Choosing simulation after already done
geometry
Simulation button situate at fight up corner (red button with letter s in the middle)
Part I.2: Boundary condition and materials
Making mesh (right click on the mesh
button end choosing Preview Mesh)
Adding more property to material
Part I.2: Boundary condition and materials
Click on the Engineering Data
button at the top of the window
For adding property
Add/Remove after that Bilinear
Isotropic Hardening
Part I.2: Boundary condition and materials
Adding more property to material
Choosing different properties as Yield Strength and Tangent Modulus
Adding more property to material
Part I.2: Boundary condition and materials
Bilinear Isotropic Hardening
MATERIAL 1Tangent Modulus2*105 MP
MATERIAL 2Tangent Modulus
1.2*105 MP
MATERIAL 3Tangent Modulus
0.04*106 MP
MATERIAL 4Tangent Modulus
0.008*107 MP
Part I.3: Stress and Strain values
Choosing New Analysis for the
simulation (Static Structural)
Part I.3: Stress and Strain values
Choosing the supported and loaded areas using Load and
Supports button
Choose Fixed support and where to be
applied (GEOMETRY – 2 FASES)
Part I.3: Stress and Strain values
Choosing type of load which is Force and his
Magnitude (2000 N) and where it
should be applied
Part I.4: Solution and Simulation
Type of solution important for this case
Stress (von Misses) for Material
2
Strain (von Misses) for Material 3
Deformation process for Material
4
Part I.4: Solution and Simulation
Solved solutions for all tree cases (pushing button Solve)
Material 2 Material 3 Material 4
Part 2.1 : View and Organization
Organization after all types of simulations in one BIG project included all 3 models
