Ballistic Impact, Laminated Glass, Crack Pattern, Transparent ArmorsAbstract
Ballistic performance of laminated glass is highly influenced by its configuration. Ballistic impact results in typical glass failure pattern, featuring a central Hertzian cone comprising of splintered glass and a spider web like cracking pattern around the cone with circumferential and radial cracks. The extent of damage varies, depending on the projectile materials. The aim of this research was to numerically compare three projectile materials, Armor steel, OFHC copper and Armco iron in reference to damage of the laminated glass (LG), considering crack pattern and the depth of penetration, for the constant velocity of AK-47 projectile. The numerical analysis concludes that, copper projectiles inflicted more damage in comparison to other two materials.
