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

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

Answer:

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).

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

Under this link, you can find a full set of verification examples to this material model:


The material model itself is explained in several technical articles of our Knowledge Base:
