mixed hardening

Hello everyone,

I'm last year PhD student. I would appreciate if someone could advice me about active research groups in Computational Plasticity (material models, hardening models, yield criteria, UMAT) in California or Australia.

I'm looking for an interesting research group to find a post-doc but I don't know from where start.

Thansks to everyone!!

Hi,

I'm working in a cyclic loding metal deformation, and I'm interesting about mixed hardening models.

I need help to know what is the "Lemaitre and chaboche(1990)" mixed hardening model, do enyone know? Is similar to the Amstrong-Frederic model??? How is represented the isotropic hardening?

Thanks!
