Mooney Membrane Material

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:

1. J or the determinant of the deformation and equal to V/V₀.
