  • UMAT or VUMAT to model Orthotropic Material behaviour

    Dear Colleagues,

    I am looking for a UMAT or VUMAT to model Orthotropic Material behaviour. There is by default the Hill's criterion via Abaqus CAE for anisotropic material modeling, but I want to develop something further for my final model.

    In this case, I am trying to find a V/UMAT for Hill criterion.

    I would be thankful if you might share your experiences with me.

    Best regards,

    I have written many of these, they are part of the PolyUMod library.
