I had finished my ph.D by using UMAT.

That's nice.
Can you tell me what kind of problem did you handle with, Stastic anlysis or dynamic anlysis and in which field?
  
I am very interested in contacting with you if you are also interested.

为什么不谈得详细一点呢。UMAT毕竞是一个很技术难度的问题。

would you like to introduce your thesis?:I

static analysis
rate-dependent Non-yield surface anisotropic constitutive law.
and applied to analyze deep drawing.

It seems that fit me research. mikejwg, Can you help me find the problem of my UMAT running:
I have my own constitutive equations and several material parameters which are functions of stress.  When I put  the constitutive equation into UMAT and trying to run it there is such a situation appears, the job can't be run and there is no erro mesage give out. Have you ever met such problem and how do you solve it? By the way, how do you deal with the material parameters which are functions of stress?
  
Thank you very much for your patient and reply.
