Define the isotropic or anisotropic elastic behavior via MP commands.
Bilinear isotropic hardening is defined by providing the tangent modulus (TB,BISO).
The constants can be defined as a function of temperature (TB,,,NTEMP), with temperatures specified for the table entries (TBTEMP).
TB,BISO -- Bilinear Isotropic Hardening Specifications
NTEMP:Number of temperatures for which data will be provided. Default = 1. Maximum = 6.
NPTS:Not used.
TBOPT:Not used.
Specifying the Constants
After defining the material data table (TB,BISO), input the following constants (TBDATA):
| Constant | Meaning | Property |
|---|---|---|
| C1 |
| Yield stress |
| C2 |
| Tangent modulus |
