IntroductionThe role of a ceramic tile in the defeat of an armor-piercing (AP) projectile is to erode and decelerate the projectile. The phenomenon called dwell or interface defeat is where the impacting projectile flows radially outward (erodes) along the surface of the target, usually ceramic, with no significant penetration. During dwell, the …
