Need user material Fortran code for viscoelastic
Tue, 2010-07-13 12:27 - tomas
Where I can find the subroutine of a user material Fortran code for Viscoelastic constitutive model?
Does anyone has the subroutine for LS-DYNA ?
Can anyone help me?

UMAT for viscoelasticity
You can find one in my PhD thesis

Good luck !

Hi, Richter, So kind you
Hi, Richter,
So kind you are, and I really appreciate you very much.
But currently I use the program LS-DYNA, not ABAQUS.
Does anyone has the subroutine for LS-DYNA ?
Thanks.
