Detailed Description

template<SizeType TVoigtSize = 6>
class Kratos::VonMisesPlasticPotential< TVoigtSize >

This class defines a plastic potential following the theory of Von Mises.

If the plastic potential is of vonMises (cylinder) type, on can see that the plastic strain increment tensor is in principle the scaled deviatoric stress tensor, hence principal directions coincide. When the yield and plastic potential surfaces are plotted in principal stress space the resulting surface will be a circular cylinder for Von-Mises. This means that both yield and strength are dependent on intermediate principal stress, sigma_2

Template Parameters

TVoigtSize

The number of components on the Voigt notation
