To Define an Elastoplastic Material
1. Select File > New or click on the Materials dialog box to open the Material Definition dialog box.
2. Type a Name for the material. In the Description box you can write a detailed description of the material.
3. Select Isotropic for the Symmetry type of the material on the Structural tab.
4. Select Elastoplastic to define the Stress-Strain Response of the material. The Isotropic Hardening Law area appears. Define By Tests is selected by default.
5. Click Edit to open the Plastic Hardening Law Definition dialog box. Define the material model using experimental stress-strain data for the material.
6. To define an elastoplastic material without using experimental stress-strain data, clear the Define By Tests check box and select a hardening law from one of the following:
Linear Hardening
Perfect Plasticity
Power Law
Exponential Law
Specify the relevant material constants based on the selected hardening law.
7. Specify the value of Coeff. of Thermal Softening for the material.
8. Specify the Tensile Yield Stress for the material. This field is highlighted with a red * since it is a required field.
9. Specify appropriate values in the remaining fields on different tabs of the Material Definition dialog box.
10. Click Save To Model to save the material definition to the current model. The material you created appears in the Materials in Model list on the Materials dialog box. Click Save To Library if you want to save the material definition to the material library.
The material is added to the database but is associated with a model or part only when you assign it to the model.
After you assign an elastoplastic material to your model you can run a Static Analysis of Models with Elastoplastic Materials for the model.
