N2 - The mechanics problem in structural design of earth penetrating weapons (EPW) has been presented in this paper. There exists a maximum penetration depth for a pure KE projectile when its geometric configuration and impact conditions are specified. However, the structural optimization of EPW, especially the mechanical design of projectile body, is quite beneficial to improve the penetration capability. Analyses are conducted on designs of projectile nose, warhead rear cover, backfill ratio, projectile shape, materials, and the scaling law as well as the design of concrete target. Some examples are given to demonstrate the theoretical results.
