In reply to vumat for isotropic perfect plastic

Hi everyone. I would like to know how to get started with a VUMAT subroutine for multiphases for example a subroutine for pore water and sand. It could be helpful when anyone could share VUMAT subroutines for learning such complex programmings. Could be appreciated when some one teaches with equations. thank you.

hello

Hello

see Abaqus Verification Manual

4.1.28 VUMAT: rotating cylinder

You need to modify the code if you simulate in 3D.

Good luck

you didn't define "third"

you didn't define "third" .... third should have value in this line ...

smean = third*(s11+s22+s33)

may be there are some other mistakes .....
