DC octahedral shear strain¶

Module: solid

Category: materialprop

Type string: "DC octahedral shear strain"

Parameters¶

This feature has no parameters.

The material type for octahedral strain damage criterion is DC octahedral shear strain. For this criterion,

\[ \Xi\left(\mathbf{F}\right)=\sqrt{\frac{2}{3}\text{dev}\mathbf{E}:\text{dev}\mathbf{E}} \]

where \(\mathbf{E}\) is the Lagrange strain tensor.
