Development of a Projectile Penetration Theory;Report 1. Penetration Theory for Shallow to Moderate Depths.

摘要

Previous work in penetration theory, based on the theory for dynamic expansion of a spherical cavity in a compressible strain-hardening medium, is extended to include the effects of nose shape, layered targets, and oblique impact. Parametric implications of the theory are investigated, and governing parameters are defined. Theoretical results are compared with experimental and empirical results and with two-dimensional finite-difference solutions; good agreement is obtained when the penetration resistance of the target due to shear is comparable with that due to inertia.
