Abstract:

Records of the motion of the penetrator target interface have been obtained for impacts of steel long-rod penetrators against rolled homogeneous armor targets. Insulated wires inserted in drilled holes in the targets are used as switches which close when the penetrator contacts the wire. The results show a high penetration velocity immediately after impact, a rapid decrease to a nearly constant velocity, then an apparent velocity increase when the rear surface of the target fractures.
