WebApr 7, 2011 · This has been previously done in Ansys, resulting in a maximum von mises stress of 3.82e8 Pa. Everything I have tried in Comsol, however, results in a von mises stress about a magnitude higher (~5.34e9 Pa). This cannot be the true von mises because it would mean the material fails (ultimate stress is 517 MPa), and experimentally I know this is ...
