    Simulation of shear banding/strain softening in ABAQUS

    Dear IceBreakerSours , Thank you very much for your reply. Yes I have tested it on single element / 8 element (3D) cases and the results seems fine to me. There is no error in completing those tasks. And the subroutine seems working fine if I use the geometric as a cubic shape, but if I...

    Simulation of shear banding/strain softening in ABAQUS

    Dear all, I am trying to simulate shear banding in single crystal (i.e. copper) using ABAQUS. I have written both UMAT and VUMAT for the single crystal plasticity, and here is what I do to introduce shear banding : first I adopted a strain-softening constitutive relation, which sets the...
