Abstract

This paper introduces an analytical model for oblique and normal penetration of conical projectiles into multi-layer thin metallic targets. Target layers could be arranged either in space or in direct contact to each other. They could also be selected from the same or different types of materials. This theory could be used for penetration in monolithic thin targets as well. In the case of perfect penetration in multi-layer metallic targets with optional angles of impact, this model could estimate ballistic limit and residual velocities, and the duration time of penetration. In this model, the energy required for the deformation of the target material and petalling formation (which includes plastic, dynamic and bending works) have been calculated. The results obtained from the above model have been compared with experimental and theoretical results of other researchers and good agreements were observed.
