KETAHANAN BALISTIK LEMBARAN BAJA PADA BERBAGAI SUDUT TEMBAK

Abstract

Results of study on the performance of 0.4 mm mild steel plate when impacted by 4.5 mm diameter steel ogive-shaped projectile at 45^o, 60^o (oblique impact) and 90 ^o (normal impact) angles of attack are presented. The projectiles were fired at highest velocity using air riffle gun. The target-holding fixture was located at a distance of 2 m from the gun. Experimental results show that steel plate provides protection at 45^o and 60^o obliquity, but fails to provide protection at angle of attack of 90^o (normal impact)
