Abstract

This paper presents ballistic limit velocity results of a variety of materials generally used in warships. Ballistic limit velocity is the velocity required for a projectile to penetrate a target with 50 percents of time and is widely used as a measure of armour bulletproofing. For this study, live fire experiments were implemented using AK-47 $7.62{\times}9mm$ mild steel core as a projectile as well as various thickness warship materials as a target. Also, methods of MIL-STD-662F, NIJ-STD-0101.06 and support vector machine were applied to measure the ballistic limit velocity and then their results were graphically analyzed for comparison. The minimum of their results was considered as the ballistic limit velocity in a conservative way.
