THE HIT POINT DEPENDENCE IN THE INTERACTION BETWEEN LONG ROD PROJECTILES AND EXPLOSIVE REACTIVE ARMOUR

Abstract

Long rod projectiles interacting with explosive reactive armour consisting of two flyer plates sandwiched around a high-explosive material is studied numerically and experimentally to understand the influence of hit point on the fracture and deformation behaviour of the projectile. The results shows that fracture, deformation and consumption of the projectile occurs mainly due to interaction with the plate moving in the same direction as the projectile. As the time span of this interaction is sensitive to the hit point, the hit point dependence should be taken into account when considering using explosive reactive armour as protection.
