I try to get a better understanding of the meaning of the output vector for stresses in femap, and I'm a bit confused now!!
With femap, we can get for a plate element, X normal, Y normal and XY shear stress. So I believe these are the components of the stress tensor.
But X and Y are relative to each element right? (X direction is from 1st to 2nd node).
So what I don't understand is when femap gives X normal stress, what is X? is it the global CS?
Also if the stresses are averaged from adjacent nodes, but the stresses are from elements which have different orientation; how accurate this is?
I have probably missed a point because I now don't know how to interpret the output from femap!
Thanks for your help!!
