- For the Nonlinear Elastic, Plasticity – von Mises, and Plasticity – Tresca material models, you can define a stress-strain curve.
Some materials in the SolidWorks Materials library have stress-strain curves defined for use with the plasticity and nonlinear elastic models for nonlinear studies. These materials are identified by showing (SS) attached to the end of their names in the list box. The reference for the stress-strain curves is Atlas of Stress-Strain Curves (2nd edition), ASM International .
- For the HyperElastic Mooney Rivlin and HyperElastic Ogden material models, you can define a curve of stretch-ratio (deformed length/undeformed length) versus nominal stress (force divided by the initial area) based on experimental data from the following types of specimen tests:
|Units||Sets the units used in the curve for the temperature (X-axis) and the selected material property (Y-axis). Strain and stretch-ratio are dimensionless.|
|Curve data table||Enter the curve data in the appropriate locations in the table.
You can use copy and paste to populate the table.
|File||Imports the curve data from a Curve Data Points File (*.dat).|
|View||Displays a graph for the material property variation with temperature.|
|Delete||Deletes the selected data row.|
