HOLE GROWTH IN THIN PLATES PERFORATED BY HYPERVELOCITY PELLETS

Abstract

An experimental study has measured hole growth rates in thin plates impacted by hypervelocity pellets. These hole growth rates were obtained for 0. 85 mm thick plates made of aluminum, copper, and cadmium impacted at 5-7 km/sec with 3.18 mm spheres of like material. The growth process was found to be a two stage process. Results are compared with the numerical predictions from a two dimensional impact code. These dynamic results are combined with observations resulting from a catalog of over 400 hole corpse measurements to form a qualitative model of thin plate impact.
