My Von Mises number from analysis is 242MPa but when I try to calculate it from analysis P1, P2 and P3, I do not get the same number, what I do wrong.
Is your Von Mises, P1, P2, and P3 stresses from the same node?
Thx, Wayne, I find out why I do not get correct answer, I am OK now.
If you could tell us what was going wrong, it would help other people out who might run into the same problem.
You replied to Wayne that the stresses were all from the same node, but marked his as the correct answer, so it is not very clear what was happening.
