Dear specialists,
as part of another ABAQUS UMAT, I am looking for the Fortran coding of a 3D Mohr Coulomb Plasticity or alternatively for a 3D Drucker Prager Criterion. I want to implement one of this UMAT=B4s in another UMAT I programming at the moment. I would be very thankful if there is any possibility to get such a UMAT.=20
With best regards, edmarc
