# How to use failure criteria in isotropic material (NASTRAN)

I'm quite new in NASTRAN enviroment, and I am wondering how to use failure criteria which I can define when creating my isotropic MAT1 material for 1D elements (like CBEAM).

From the Quick Reference Guide, (MAT1) I am able to define 3 stress limits during the material creation.

What type of related output should I expect? Can I obtain failure indices or security indices? (like PLY composites) I've tried to launch a SOL101 but I can't figure out how to obtain these values, unless they are in the colums of F06 file named M.S.-T and M.S.-C (I can't find a reference in the guide, though!)

Other types of SOLutions effectively use these stress parameters? I'm actually interested in SOL111.

Thank you in advance for any help.
