Abstract：According to the theory of short wave and internal friction model，the resistance of projectile is obtained from relationship of momentum conservation on the wavefront and continuum condition of the surface of projectile. The ratio scale relationship of penetration and perforation is revealed by the relationship energy transfer in the process of fragmentation zone to radial crack zone. A new generalized formula for calculating the penetration depth of non-deformable projectile is obtained from the projectile. The comparison between experiential formula results and the theoretical results verifies the validity of theory.
