Some other differences which you may encounter later. MSC.Nastran does not use corner stress output for nonlinear results. NEiNastran takes plastic strain and equivalent stress at integration points and extrapolates these to corner values to better predict stress and strain with coarse meshes...
Hi Thomas,
We ran your model in NEiNastran and think we know what the problem is. Use the EQUIVALENT STRESS and not the VON MISES STRESS. The difference between the two is mainly with material nonlinear analysis. NEiNastran computes the equivalent stress at the integration points and report...
