Hi @KubliJ,

 

Typically for composites, we're looking at the Failure Index.  In Autodesk Nastran In-CAD, the output will include COMP MAX FAIL INDEX which is the overall for all layers.  You can also see COMP MAX FAIL INDEX PLY which will give you the ply number reporting this maximum value.

 

Additionally, we have a parameter to switch to strength ratio if that type of output is preferred over failure index.  Please let us know if this covers the request.  Thank you,

 

Mitch
