Concrete Penetration and Ricochet Testing of Two Projectile Types

Abstract

The purpose of the work was to develop penetration/ricochet data for two projectiles launched against 5,000 psi concrete targets and, in addition, to measure the axial stress on the nose of a projectile during concrete penetration. The program employed projectiles 3.35 inches in diameter and approximately 27 inches long with two different nose shapes. Three different types of targets were used. Targets consisted of concrete slabs, 8-ft square and with thicknesses of 4 inches, 12 inches and 30 inches. A ricochet relation was developed from the data and the results seemed to correlate well with some previous work. One test was conducted in which an on-board shock resistant recorder was used to collect a time history of the output of a pressure transducer installed in the nose of a projectile. The results of the experiment were compared with a hydrodynamic code calculation and showed reasonable agreement for early times.
