Finite Element Simulation on Ballistic Impact of Bullet on Metal Plate

For both military and civilian vehicles, ballistic safety systems frequently use high-strength Titanium and Aluminum plates. The choice of alloy is therefore based on its intended usage, ballistic performance, and safety for them. In this study, the effect of a bullet on Titanium and Aluminum alloy plates with fixed edges on both sides is examined. The effects of bullet thickness and impingement angle on Titanium and Aluminum alloy plates were examined using simulations. These simulations were carried out in Ansys Workbench using the Finite Element Method. Simulations using both material models also revealed a distinct variation in the plate’s deformation. The targeted plate was impacted at a 45° oblique angle with velocity of 830 m/s in every test. The findings demonstrated a crucial slant angle of 45° where the piercing operation transitions to ricochet. The other simulation was run to ascertain the plate thickness where the piercing operation transitions to embedment.
