Impact of ogival nosed Projectiles on Al 1100 H-12 thin Plates : Numerical Study

Abstract

This study examines the ability of thin metallic aluminium 1100-H12 targets to absorb energy in various deformation modes during perforation. The targets are impacted with hard steel cylindrical projectiles having a diameter of 19 mm with ogival nosed profile. At oblique angles of 0°, 15°, 30°, and 45°, the target plate is impacted at different velocities varies from 124.00 m/s to 500.00 m/s. The simulations are conducted in ABAQUS/Explicit solver with the Johnson-Cook elasto-viscoplastic material model for each target plates. It is observed that the ballistic performance of target used in simulation study and experimental study is approximately equal. The main purpose of this research is to find out how the velocity drop for the target plate and projectile is influenced by the angle corresponding to impact at different incidence velocity. This study also determined the temperature generated at the target surface during impact.
