◆ calculate_second_piola_kirchhoff_stress()

inlinevirtual

Calculate the contravariant 2nd Piola Kirchhoff stress tensor. Arguments are the covariant undeformed (stress-free) and deformed metric tensors, g and G, and the matrix in which to return the stress tensor.

Implements oomph::ConstitutiveLaw.
