Dear
I want to develop HASHIN and PUCK damage initiation and progressive damage with gradual degradation material properties(energy based) in composites with continuum elements (3D stress) with UMAT subroutine and delamination with damage initiation and progressive damage of cohesive element for composite pipe under internal pressure.I have developed a UMAT and it works well but not with the HASHIN or PUCK criteria, I cannot compile when I make the formulas of HASHIN 1980 I would like, if I can find someone with experience to solve this problem.
Thanks in advance
