An Investigation of Forces on a Projectile during Perforation of Thin Aluminum Plates

Abstract

The reverse forces encountered by projectiles during ordnance velocity perforation of thin aluminum plates were determined for four projectile configurations and three plate thicknesses. The investigation was conducted by holding simulated projectiles stationary and impacting them with aluminum plates. Strain gages bonded to the stationary targets were used to obtain a strain versus time record during perforation; this was subsequently converted into a perforation force record by application of strain wave propagation and linear strain theories. The projectile noise configurations investigated include two cones, a hemisphere and a flat ended cylinder. Peak perforation force and projectile efficiency comparisons were made with results from other investigations. (Author)
