Density change subroutine
Density change subroutine
(OP)
Hi
I have a question about possibilities implement user-material subroutine included changing material density. I have thermal problem where I should assume diffrent density. I would like implement changing density in every material element and watching strain distribution as a result of diffrent density.
Is it possible in Abaqus? If yes which subroutine i should use.
Thanks for help

RE: Density change subroutine
If it just depends on temperature then you can do this already in the specification of ABAQUS material properties. If it's a little more complicated you could use field variables perhaps:
