Detailed Description

CompressibleMooneyRivlinMaterialLaw

A Mooney-Rivlin isotropic compressible hyperelastic material law for finite elasticity

The law is given by a strain energy function W(I1,I2,I3) = c1 ( dev(I1)-3 ) + c3(J-1)^2

where (assuming Ii are the principal invariants of C, the Lagrangian deformation tensor, I1=trace(C), I2=0.5(trace(C)^2-trace(C^2)), I3=det(C)): J = det(F) = sqrt(I3) dev(I1) = I1 * J^(-2/DIM) is the first invariant of the deviatoric part of C

Note T(E=0) = 0 regardless of choice of c1, c3.

NOTE: this is really just a NEO-HOOKEAN law at present - the c2 (dev(I2)-3) term hasn't been added yet...
