You may need to look at one of the Explicit codes for that type of penetration. In Fluent we'd look at erosion as a long term problem. You'll need a separate topic for that in the Structures/Mechanical section of the Community. 

Shocks are line/surface effects (2d/3d) so you could plot the shape of the shock on an isosurface using an xy plot and then overlay the lines to see the shock evolution.
