Mooney-Rivlin Rubber Material
The regularized Mooney-Rivlin material for compressible rubbers uses the following expression to measure strain energy.
where and are two material constants and is the bulk modulus.

Syntax
material MoonetRivlin (1) (2) (3) (4) [5]
# (1) int, unique tag
# (2) double, bulk modulus
# (3) double, A_{10}
# (4) double, A_{01}
# [5] double, density, default: 0.0
Remarks
Nonlinear geometry switch shall be turned on in related elements.
The model takes the Green strain as input. To implement any elements that incorporate this material model, the Green strain in Voigt notation shall be passed as strain input.
