A Scaling Law for APM2 Bullets and Aluminum Armor

Abstract

We developed a scaling law to predict the ballistic-limit velocities for 7.62 mm APM2 bullets that perforate armor plates. Data from 5083-H116, 5083-H131, 6061-T651, 6082-T651, and 7075-T651 aluminum armor plates with thicknesses between 20 and 60 mm show that the ballistic limit velocities are proportional to the square root of the product of plate thickness and strength term. The strength term is derived from a cylindrical cavity-expansion analysis that requires large-strain compression data.
