Abstract:
A comparison has been drawn on ballistic responses of different types of perforation in high hardness armor plates against armor piercing projectiles through experimentation in the research. The ballistic response of an aluminum base armor plate and a combination of different types of high hardness perforated armor plates and aluminum base armor plate were determined against 7.62 mm armor piercing projectile. Three different perforations were made in high hardness perforated steel plates i.e., circular, diamond and slot perforations. The base armor plate alone was not able to stop projectile and it penetrated throughout. While when the same base armor high hardness perforated armor plates, projectile was stopped. Depressions were formed on the surface of the base armor plate from the impact of the projectile fragments. Video of impacts were also recorded through high speed camera.
