Research of the projectile’s layout for penetration capability through metal targets

Abstract

Abstract Present paper deals with research of behavoir metal targets impacted by ogive-nosed and blunt-nosed projectiles at 290 m/s. A complex continuum mechanics model was used to describe the material behavior under impact. Numerical modeling of perforation of metal plates with projectile are performed using IMPACT computer code. As test problem, single-plate ballistics test was modeled. In order to verify the model and method, the ballistic experiment was simulated. Good agreement with experimental data was obtained. The results of numerical simulation are shown as computed “Projectile - target” configurations, time dependences of the residual projectile velocity and the computed values of the residual velocity. It has been found that by changing the projectile layout it is possible to increase the residual velocity up to 80%. The deformation mechanisms of targets resulting from different noses shapes of projectile were also studied.
