hi Mr. Jannesari
this is Mehrmashhadi
i think u remember me not in ikco/npd but in mail and such conversations.
recently i'm faced with a problem in FE. i'm sure u can help me.
and this is the problem:
in an some analysis for instance axis symmetric i see Sx and Sy etc. stresses much more than Von stress. in model, material is multi-linear isotropic. i attached some pictures to see it is correct
method of analysis is so simple. left line is axisymmetric BC, right line is a rigid die all DOF constrained except X-direction.
what do u think of this misunderstanding???
i mailed this to a_jannesar@yahoo.com too
