If you release a structural component with a nonlinear elastic material again, the strain goes back on the same path. In contrast to the Isotropic|Plastic material model, no strain is left when completely unloaded.
You can select three different definition types:
- Standard (definition of the equivalent stress under which the material plastifies)
- Bilinear (definition of the equivalent stress and strain hardening modulus)
- Stress-Strain Diagram:
- Definition of polygonal stress-strain diagram
- Option to save / import the diagram
- Interface with MS Excel
Background information about the orthotropic material model can be found in this technical article: Yield Laws in Isotropic Nonlinear Elastic Material Model .
