Defining Failure Criterion for Orthotropic Materials Using Tsai-Wu Yield Criterion

If you want to define the failure criterion s for an orthotropic material, you have to define the orthotropic plastic material under Material Model (Image 01).

1 Material Model

The yield criterion will be taken according to the Tsai-Wu criterion (Image 02).
