Hello,

I am trying to assign a failure criteria based on strain. For example, I want to be able to remove or replace the material properties of elements that reach 0.9% strain, or do the same thing when the principal strain of an element exceeds 10000 microstrain (these figures are from literature).

 

The MATF card only takes stresses. How can I implement these strain-based criteria?

Thanks.

MATF bulk data card supports multiple failure criteria

  • PUCK, HILL, HOFFMAN, TSAI-Wu, HASHIN, or Max Strain

Right now we can only calculate Composite Failure with Shell-elements and MAT1/MAT8 Materials.
