Penetration of a rigid projectile into a multi-layered target: theory and numerical computations

摘要

The main objective of the present work is to develop an adequate analytical model for penetration of multi-layered targets by rigid projectiles. The theoretical approach presented here generalizes the single- layer models described in [1, 2]. As in [1, 2] an analytical solution is developed for which the momentum equation is satisfied pointwise in the target region, while the boundary and continuity conditions are sat- isfied only approximately. Also, a single particular velocity field is assumed for all target layers.
