Nastran Request for Equivalent Plastic Strain in Hypermesh

Nastran Request for Equivalent Plastic Strain in Hypermesh


Dear All,

I am new to non linear analysis and using MD nastran and Hypermesh 10.0. I am running Sol 601 and request all outputs of strain in hypermesh. The solution runs fine and when I post process the only strain I get out of the .Op2 file is strain(t). Does anyone know how i can get the EPS to post porcess. I probably need to request it in the .BDF file prior to solving but believe HM may not support this.

I see that Nastran writes out a .marc file which probably has the output request for Equivalent Plastic Strain. The default marc solution results file .t16 reports component of plastic strain tensor (t)as default. it looks like I need postcose 27 to get EPS.

This is where I need the help. What values do I request in Hypermesh to cause nastran to tell MARC to request the EPS or postcode 27?

Please does anyone have an answer. I appreciate some feedback.
