Abstract

Perforation, especially the break-through of a projectile at the rear surface of a rolled steel plate is a highly complex event. Shock wave effects and a large amount of deformation cause failure of the target material at the exit surface of a barrier. The perforation failure processes are strongly influenced by target material (ductile, brittle), projectile shape, and perforation velocity. Two different modes of peripheral fragments are formed in the rolled steel plate by the perforating projectile: fracture parallel and perpendicular to the rolling texture of the steel plate. The formation process of this fracturing, beginning with buckling of the exit surface in the vicinity of the break-through point of the projectile, and ending with the break-out of the residual projectile is observed by means of flash X-ray techniques. Steel and high density metal rods are used as projectiles. A smooth bore powder gun allows the acceleration of these projectiles up to impact velocities of 1800 m/s. Three, respectively four X-ray sources are aligned at the rear surface of the target for cineradiography of the buckling and fracturing processes.
