[Constitutives] MC J2 correction #591

Closed bodhinandach closed 4 years ago

bodhinandach commented 4 years ago

The PR fixes the bug to compute the stress derivation of the j2 deviatoric stress invariants, which are included in the computation of drho_dsigma, dj2_dsigma, and dj3_dsigma. The 2.0 coefficient is missing to account for the symmetric of the off-diagonal components, i.e. S12=S21 -> S12+S21 = 2.0*S12.
