Detailed Description

This law defines an hyperelastic material according to the Saint-Venant–Kirchhoff formulation for 2D-plane stress cases.

The simplest hyperelastic material model is the Saint Venant–Kirchhoff model which is just an extension of the linear elastic material model to the nonlinear regime. More info https://en.wikipedia.org/wiki/Hyperelastic_material#Saint_Venant%E2%80%93Kirchhoff_model
