Hi all, as of title. I face the problem that no matter what kind of JC damage parameters were used (even lowly ductile), elements failure and deletion were not observed in the LS-DYNA solver.
It should not be problem with the setup, other failure modes such as principal and equivalent works fine. It is only that JC damage parameters did not work.
I have success with failure using the same parameters with the Autodyn solver and hence the problem definitely does not come from the parameters either.
