DC von Mises stress¶
Module: solid
Category: materialprop
Type string: "DC von Mises stress"
Parameters¶
This feature has no parameters.
Description¶
The material type for von Mises stress damage or yield criterion is DC von Mises stress. For this criterion,
\[
\Xi\left(\mathbf{F}\right)=\sqrt{\frac{3}{2}\text{dev}\boldsymbol{\sigma}:\text{dev}\boldsymbol{\sigma}}=\sqrt{\frac{1}{2}\left[\left(\sigma_{1}-\sigma_{2}\right)^{2}+\left(\sigma_{2}-\sigma_{3}\right)^{2}+\left(\sigma_{3}-\sigma_{1}\right)^{2}\right]}
\]
where \(\sigma_{1}\), \(\sigma_{2}\), \(\sigma_{3}\) are the principal values of \(\boldsymbol{\sigma}_{0}\left(\mathbf{F}\right)\).
