Submitted by sbagherzadeh on

Dear all,

Hi

I am phd student of mechanical engineering. I am working about dislocation density based model for plastic deformation. I wanna write UMAT for describe used material behavior. Can everyone give me experiences about DD model in FEM? Please help me about writing UMAT for this issue.

 

Thank you,
