Ballistic Resistance of Finite Plate Targets Against 7.62 NATO AP Ammunition

In the present study, 12 mm thick single and in-contact multi-layered target configurations composed of Armox 500 T and mild steel materials have been investigated against 7.62 NATO AP projectiles. The effect of projectile–target surface interaction properties on the ballistic resistance was studied by varying the tangential friction coefficient between projectile and target. Finite element analysis was carried out in ABAQUS/Explicit software. The numerical study was verified from previously published ballistic study on the same materials. JC constitutive model was used to simulate the material behavior of the target, whereas the projectile body was modeled as analytical rigid instance. The observed impact behavior of different target configurations was compared in terms of velocity drop in the projectile incident velocity, deformations, and strain energy absorption in the target configurations.
