The material type for von Mises stress damage criterion is “DC von Mises stress”. For this criterion, $$\Xi\left(\mathbf{F}\right)=\sqrt{\frac{1}{2}\left[\left(\sigma_{1}-\sigma_{2}\right)^{2}+\left(\sigma_{2}-\sigma_{3}\right)^{2}+\left(\sigma_{3}-\sigma_{1}\right)^{2}\right]}$$ where $\sigma_{1},\sigma_{2},\sigma_{3}$ are the principal values of $\boldsymbol{\sigma}_{0}\left(\mathbf{F}\right)$ .
