Iterations in VUMAT

Dear all,

I' m trying to make a model in VUMAT for shape memory alloy based on Lagoudas 's thermomechanical constitutive model. It seems that It's necessary an iteration to evaluate the thermoelastic prediction.

My questions are : is it possible to use an iterative loop in the VUMAT or it's better to avoid it??Could someone suggest me a different way so that I can avoid the iterative loop?

Many thanks,

Cece

you can do it by interaction method.  you also can take advantage of the mini incremental time step to solve the related variable in vumat directly.

Hi hua_2001,

thanks for answering.

Could you suggest me a good paper or book about interaction method? Have you ever worked with shape memory alloy.I find difficult to create the dipendence from martensitic volume fraction.

Any suggestion will be appreciate.
