How can I define failure criterion s such as Tsai-Wu for orthotropic material?

Answer

If you want to define failure criterion s for orthotropic material you have to define a orthotropic plastic material in the Material Model (picture 1).

The yield criterion will be done according the Tsai-Wu criterion (picture 2). 

By this Link you can find a full set of verification examples to this material model. 

The material model itself is explained in several Knowledge base articles.
