Hello,

I want to do a case hardening problem to calculate the hardens number and depth of hardening using carburization process. I read some research article where they clearly stated that that it has to be achieved through the mass diffusion analysis followed by coupled temperature displacement analysis. and all the hardness parameters then can be calculated via UMATHT subroutine. Since I don't have any reference for UMATHT code for this kind of simulation, I request if any of you solved this with UMATHT subroutine help me with sample code start this analysis.
