Thanks @SW. I did not have this confusion before, however, to double check I read about the NOCOMPS card that is used to output the stress for an equivalent homogenous section. The item in the list that bothered me was that "when Z0 is not defined as -0.5 times the thickness of the laminate, equivalent stresses output are incorrect". Hence the confusion. If you could explain in short (if that is a possibility!) how to interpret the result, it would be of much help to me (and maybe more people).
Thanks again!
