I'm running MSC NASTRAN v 70.5 sol 101 with PCOMP's CFRP laminates and I get drammatical differences between NASTRAN v70.5 ply stress output, ESA software (ESACOMP v 2.0) when I use unsymmetric laminates. ESACOMP's results are confirmed by home made already tested software, so the problem seems to be in the way that NASTRAN calculates ply stressed from element strains.

Has somebody had the same problem?

Thanks

You can answer in french or spanish if you want...
