Sharing ABAQUS UMAT and VUMAT subroutines
I have noticed that a lot of people are using UMAT and VUMAT material model
subroutines for their researches. However, most of these subroutines do not
find their way to free code market and remain in the hands of the developers.
Therefore, a lot of wheel re-inventing has to be done by other people. Since
development and testing of a material subroutine takes a damn long time, I
think it is a good idea if each of us can share the subroutines she has
developed with the others. I know that a couple of subroutines are publicly
available and many other people also know that. Please comment about less-known
freely available subroutines.
To be more specific, I think it would be useful if people can comment about
following highly demanded UMAT subroutines:
1.Cohesive zone elements models
3.Gurson-type ductile fracture models
