Modeling of Ballistic Impact of Fragment Simulating Projectiles against Aluminum Plates

In this paper, the ballistic impact test is described in which fragment simulating projectiles (FSPs) have been used against thick plates made of an aluminum alloy. To perforate the plates, the projectiles must have reached velocities higher than 890m/s. The failures of targets are modeled in the numerical simulation using the Lagrangian Finite Elements Method with the Johnson – Cook constitutive model coupled with the cumulative-damage fracture model implemented in the *MAT_107. *KEYWORDS: BALLISTIC IMPACT TEST, ALUMINUM, FRAGMENT SIMULATING PROJECTILE (FSP), LAGRANGIAN SOLVER, *MAT_107
