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
rPredictiveStressVectorThe predictive stress vector S = C:(E-Ep)
rDeviatorThe deviatoric part of the stress vector
J2The second invariant of the Deviator
rGFluxThe derivative of the plastic potential
rValuesParameters of the constitutive law

template<SizeType TVoigtSize = 6>
static int Kratos::RankinePlasticPotential< TVoigtSize >::Check ( const Properties rMaterialProperties)
inlinestatic

This method defines the check to be performed in the plastic potential.

Returns
0 if OK, 1 otherwise
