Can someone help me to understand why the impactor bounces off the laminate instead of punching through it? In hyperview there is stress, but then it bounces.
What did I do wrong?
Thanks

    Hi

    In order to the perforation happens, you need to define the criterion for material failure.

    the /FAIL  does not have limit value , e.g., strain to the element deletion.

    the /MAT has the eps_max set, but maybe it is too large. eps_max is plastic strain, it is not the total

     

    I hope this is helpful.
