The experimental investigation for penetration depth and shape of aluminum alloy plates by 5.56mm ball projectile with striking velocities between 350 and 750㎧

고속충격시 볼탄에 의한 알루미늄 합금의 관통 깊이와 형상에 관한 실험적 연구

This investigation describes and analyses the experimental results proper to the penetration of Al5052-H34 alloy plates of thickness 6, 12 and 16mm(T/D＝1, 2, 3) by 5.56mm ball projectiles over the velocity range 350-750㎧. All the high velocity impact tests were carried out at normal impact angle, i.e. zero obliquity. The experimental results presented the variation of depth of penetration, bulge height and diameter, plugged length and diameter with the velocity fur tests on each plate of a given thickness in order to determine the deformation shapes of 5.56mm ball projectiles and targets. Also the protection ballistic limit($V_50$) tests were conducted.
