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
