void IsotropicMaterialWithCompressionResistance::AddCompressionResistanceGradient(int elementIndex, double * invariants, double * gradient)
{
  if (enableCompressionResistance)
  {
    double IIIC = invariants[2];
    double J = sqrt(IIIC);

    if (J < 1)
    {
      double compressionResistanceFactor = GetCompressionResistanceFactor(elementIndex);
      gradient[2] += -compressionResistanceFactor * (J - 1.0) * (J - 1.0) / (1728.0 * J);
    }
  }
}

    if (J < 1.0)
    {
