*HEADING ABAQUS/Explicit benchmark problem. The problem simulates the penatration of a thin plate by a projectile. Similar to pp_velo_study but with low speed impact to allow completion of analysis without element failure. This is to simulate a balanced master-slave approach with the master surface at r=0.
