Defining density as a solution dependent variable in VUMAT (Abaqus/Explicit)?

Submitted by Shunlai.Zang on Fri, 05/06/2011 - 15:25

Hi All,

I am trying to simulate tooth deformation. It involves that the density of tooth changes with deformation. I want to know is it possible to define density as a solution dependent variable in VUMAT?

Thank you in advance!
