We have expanded the number of material models supported for Nastran solutions. These material models are applicable for each of the following situations:
- when solving nonlinear models within Autodesk Simulation Mechanical (using a Nastran processor),
- when exporting the model to the Autodesk Nastran Editor, or
- when exporting a Nastran deck using the
Application Menu
Export Third-Party FEA command.
The following table lists the additional material models by element type:
| Nonlinear Element Type | Corresponding Nastran Cards | Material Model | |
|---|---|---|---|
| Element Cards | Material Cards | ||
| Brick | CHEXA | MAT1, MAT4, and MATS1 | von Mises with Isotropic Hardening |
| Tetrahedron | CTETRA | MAT1, MAT4, and MATS1 | von Mises with Isotropic Hardening |
| Brick | CHEXA | MAT1, MAT4, and MATS1 | von Mises with Kinematic Hardening |
| Tetrahedron | CTETRA | MAT1, MAT4, and MATS1 | von Mises with Kinematic Hardening |
| Beam | CBAR and PBAR | MAT1 and MAT4 | Isotropic |
| Beam | CBAR and PBAR | MAT1, MAT4, and MATS1 | von Mises with Isotropic Hardening |
| Beam | CBAR and PBAR | MAT1, MAT4, MATT1, and TABLEM1 | Temperature Dependent Isotropic |
Note: For a list of the other supported material models and elements, refer to the Nastran page in the FEA Model Import and Export Functionality section of the User's Guide.
