Detailed Description

template<class DataTypes>
class sofa::component::solidmechanics::fem::hyperelastic::material::Costa< DataTypes >

a Class that describe a generic hyperelastic material : exemple of Boyce and Arruda The material is described based on continuum mechanics and the description is independent to any discretization method like the finite element method. A material is generically described by a strain energy function and its first and second derivatives. In practice the energy is the sum of several energy terms which depends on 2 quantities : the determinant of the deformation gradient J and the right Cauchy Green deformation tensor
