Constitutive Laws
This MPM material is in development
Material Properties
The unusual task for this material is to use multiple Gk and tauk properties (all with the same property name) to enter a material with multiple relaxation times.
| Property | Description | Units | Default |
|---|---|---|---|
| (properties) | Enter all properties for the corresponding solid Mooney material | none | none |
| dither | Add random spread of initial orientation angles to better model compression of thin membranes | degrees | 0 |
Note that unlike a solid Mooney material, a Mooney membrane can be incompressible by setting the Poisson's ratio of 0.5.
History Variables
This material uses one history variable:
- J or the determinant of the deformation and equal to V/V0.
