Residual velocity and kinetic energy of the ballistic simulations test on hardened medium carbon steel plate

Ballistics testing is the study of collision phenomena between projectiles and target material. Simulation with finite element is one alternative to ballistic testing that can provide detailed numerical data and specific. Validated simulations can be used as a reference for improving projectile resistant material in addition to the results of experiments test. These papers presents the effect of austenization temperature and quench media in the S45C steel plate on the residual velocity of the projectile and kinetic energy after being fired blunt projectile at a speed of 303.5 m/s with simulation base on finite element. Material data was obtained from the results of an experimental test of S45C steel plate thickness 8 mm which was austenization at 700, 800, 900°C which was quenched in water and oil media. Validation of simulations is carried out with past research. The simulation results show that the steel plate is austenization 900°C with treatment on the quench oil media can withstand the projectile better, with a projectile residual velocity of 234.46 m/s, with projectile kinetic energy of 1346.8 Joule.
