Definition of elastic material
Parameter¶
TYPE = ISOTROPIC (Default)/ ORTHOTROPIC / USER
DEPENDENCIES = 0 (Default)/1
INFINITESIMAL When specified, infinitesimal deformation is assumed
2nd Line or later¶
- In the case of
TYPE = ISOTROPIC
| Parameter Name | Attributions | Contents |
|---|---|---|
| YOUNGS | R | Young's Modulus |
| POISSON | R | Poisson's Ratio |
| Temperature | R | Temperature (required when DEPENDENCIES = 1) |
- In case of
TYPE=ORTHOTROPIC
Note: When using
TYPE=ORTHOTROPIC, the corresponding!SECTIONmust specify a local coordinate system via theORIENTATION=parameter. OmittingORIENTATION=will cause the solver to abort at runtime.
