Detailed Description

template<Concepts::DeviatoricFunction DF>
struct Ikarus::Materials::Deviatoric< DF >

The deviatoric part of the hyperelastic model, i.e., related to \( \hat{\Psi}(\la_1, \la_2, \la_3) \), is parametrized with a certain deviatoric function (DF) implemented in terms of principal stretches. The three interface functions (energy, streses and tangentModulus) are called with the argument being the principal stretches ( \( \la_i \)). The underlying deviatoric function must only implement the energy \( \hat{\Psi}(\la_1, \la_2, \la_3) \) and its first and second derivatives w.r.t the total principal stretches.

Template Parameters
DFDeviatoric function.
