    Improper Stress output

    Hi I would like to know how impact analysis for the plate attached does not have any stress ( very low stress ). I am using P1_Shell Property with QEPH element formulation and M36_plas tab MAT. please guide. Also like to know whether what to use for Stiffness Definition(Istf) for contact interface.
  2. @Ivan Thank you so much ivan. I just have another doubt with this iteration is that remaining time increases with the variation with I Energy and K energy . Is there anything to note or it is usual for a increase and decrease of time.
