Detailed Description

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

a Class that describe a generic hyperelastic material . 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.
