Hi everyone,
First of all, sorry for my english level.
Actually i'm working with abaqus to study the void closure during hot forming. The approach i used, is using a Representative Volume Element.
In the Property modulus, i did not find how to introduce a Norton-Hoff behavior law : Sigma = C * (Epsilon_dot)^m
Thank you for your answers.

If you miss a material model you need, then you could add it via a UMAT subroutine.
 
Get in touch with Simulia first and see if they have any suggestions for you. If it turns out that you will have to write a UMAT, you will need a significant amount of resources from your managers to have a chance of 'success' towards the end.
