1. The destruction mode for the ogival nose perforator is a stabbing one, while that for the flat nose perforator is a plugging one.

2. In this paper, the bistatic scattering around ogival pedestal below the top is analyzed, based on the analysis, a novel metal supporter which satisfies RCS measurement requirements is designed.

3. It is similar to the case under low speed that the tangent ogival projectile and larger ration of length to diameter can enhance the penetration, but the damage on the concrete is less serious.

4. Two models are developed for ballistic impact of thick metallic plates struck by non-deformable projectiles with conical or ogival noses by considering two interconnected perforation stages.

5. A new engineering model is developed for analysis of ballistic impact of moderately thick metallic plates struck by non-deformable projectiles with conical and ogival noses.
