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{ \mathbf{\sigma} = (\mathbf{I} - \mathbf{D}) \mathbf{C} \mathbf{\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).,
