The material type for maximum normal stress damage criterion is “DC max normal stress”. For this criterion, $$\Xi\left(\mathbf{F}\right)=\max\left(\sigma_{1},\sigma_{2},\sigma_{3}\right)$$ where $\sigma_{1},\sigma_{2},\sigma_{3}$ are the principal values of $\boldsymbol{\sigma}_{0}\left(\mathbf{F}\right)$ .
