= Deviatoric stress
{title2=$\boldsymbol\sigma_{\rm dev}$}

The deviatoric part of a three-dimensional <stress> <tensor> is $\boldsymbol\sigma_{\rm dev}=\boldsymbol\sigma-\operatorname{tr}(\boldsymbol\sigma)\mathbf I/3$. It is traceless. Adding an isotropic pressure does not change a <normal-stress difference>.
