Detailed Description

template<class TElasticBehaviourLaw>
class Kratos::ViscousGeneralizedKelvin< TElasticBehaviourLaw >

This is a constitutive law that reproduces the behaviour of viscous Kelvin material.

The definition of the Kelvin-Voigt material can be founf in Wikipedia https://en.wikipedia.org/wiki/Kelvin%E2%80%93Voigt_material The Kelvin–Voigt model, also called the Voigt model, can be represented by a purely viscous damper and purely elastic spring

        -----          ------
             |---[----|
              Damper C

Parameters

TElasticBehaviourLaw Defines the elastic behaviour of the constitutive law (can be hyperelastic or just linear elastic, or any desired elastic behaviour)
