how do i simulate a impact test on a component ? where a hammer is used to impact a screw 10 times. one impact i can simulate but after the screw impact by the hammer on the screw, the nail is deformed, now i want to impact the screw 9 times with the  hammer at the same velocity on the deformed nail. how do i simulate. repeated impacts.

Kartik,

You might want to set up a 10 step simulation (this is going to be a long simulation) and define a cyclic displacement profile on the hammer to move it back and forth. I can't think of a better way, maybe others can chip in.

What solver are you using? Explicit STR or ANSYS LS DYNA?
