Hi Goda,
Did you incorporate plasticity in your model for both analyses? In general, using explicit dynamics solver (either AUTODYN or LS-DYNA) is more appropriate for this type of simulation due to the short nature of the test and significant material nonlinearities that may arise during deformation. If you really need to employ an implicit solver, try using "Transient Structural" instead of Static Structural analysis system. Â
