Detailed Description
template<unsigned DIM>
class ExponentialMaterialLaw< DIM >
ExponentialMaterialLawAn exponential isotropic incompressible hyperelastic material law for finite elasticity
The law is given by a strain energy function W(I_1,I_2,I_3) = a exp( b(I_1-3) ) - p/2 C^{-1} in 3d, or W(I_1,I_2,I_3) = a exp( b(I_1-2) ) - p/2 C^{-1} in 2d.
Here I_i are the principal invariants of C, the Lagrangian deformation tensor. (I1=trace(C), I2=trace(C)^2-trace(C^2), I3=det(C)).
Note: only dimension equals 2 or 3 is permitted.
