The protection capability of dual flying plates against a yawed long rod of enhanced L/D is evaluated numerically, where L is the length and D is the diameter of the rod. This study is motivated by the fact that the protection performance of dual plate system is governed by the extent of interaction

β¦ Synopsis
Protection effectiveness of an oblique metallic plate against a long rod projectile has been evaluated through a threedimensional dynamic finite element computer program. The parameters considered in the simulations are the impact velocity, oblique plate thickness, gap distance between oblique plate and witness block, and obliquity. It was found that protection performance of an oblique plate was maximized in case that the ratio of line-of-sight (LOS) plate thickness to projectile diameter is around 2.0. This result may be used as a guide for the design of obliquely spaced armour structures against long rod projectiles.

The geometry and motion of long rod projectiles after penetrating thin obliquely oriented and moving armour plates were studied. Plates moving in their normal directions towards as well as away from the projectile (scalar product of velocities negative and positive, respectively) were considered. Th
