Kratos::GenericPlasticPotential< TVoigtSize > Class Template Reference

If the plastic potential is of the same type as the yield surface we talk about associated flow rules, if a different function is used, it is non-associated. For metals associated flow rules work great, while frictional materials typically need non-associated flow rules. More...

Detailed Description

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

If the plastic potential is of the same type as the yield surface we talk about associated flow rules, if a different function is used, it is non-associated. For metals associated flow rules work great, while frictional materials typically need non-associated flow rules.

This is a "template" plastic potential, please define properly your plastic potential

Template Parameters

TVoigtSize

The number of components on the Voigt notation

This script calculates the derivatives of the plastic potential according to NAYAK-ZIENKIEWICZ paper International journal for numerical methods in engineering vol 113-135 1972. As: DF/DS = c1*V1 + c2*V2 + c3*V3.

Parameters

rPredictiveStressVector	The predictive stress vector S = C:(E-Ep)
rDeviator	The deviatoric part of the stress vector
J2	The second invariant of the Deviator
rGFlux	The derivative of the plastic potential
rValues	Parameters of the constitutive law
