Hi

I defined my material and section card like below:

I am not sure how von Mises criteron can be used herein or does it look okay?

In another note, Do you know how lsdyna calculated the vin misses stress showed in lsprepost? Does it use a different formula? What I think it calculates stresses at two integration points for fully integrated shell (2 integration points) and averaged value displayed in lsprepost but not sure.
