Hi Raphael,
As a suggestion, this type of simulation (impact test) is much easier using an explicit solver. The Static Structural analysis system uses the implicit time integration method. You can employ Explicit Dynamics (AUTODYN) or even better than that, the Ansys LS-DYNA solver available in Ansys workbench that are robust for short-duration events with significant nonlinearities. Then try applying the impactor load as a velocity-based boundary condition (rather than force-based) under Initial Condition. If this is of interest, check out the course below to learn more about explicit dynamics analysis:
