Please first elaborate on
- what you are modeling - specific material/layup/etc being modeled with the PSHELL card
- the properties for your material
- what your current PSHELL/MAT2 cards are
- the reason for your question

just in general ,wanted to know what nastran do with it.
I understand it saves me the trouble of calculating a new equivelent E and thickness when modeling hc panel.
does it mean the nastran stress output will be based on equivelent thickness and not on the user defined thickness ?
I mean would,lets say, shear_stress=force/(width*Ts/T)?
and how it treats the bs 12I/T^3 ?

12I/T*3 and Ts/T is used when you are modeling a sandwich panel.
