Constitutive Law
This MPM Material is an isotropic, elastic material, but once it fails, it develops anisotropic damage. The constitutive law for this material is
[math]\displaystyle{ \sigma = ( I - D)C \varepsilon }[/math]
The elastic regime for this material is identical to a Mooney except that it only allows a Neohookean elastic regime (with G = G1 and G2 = 0).,
