Penetration and perforation process of 12.7mm FSP on plate captured by high-speed camera 2: Video (Test 2 of configuration 2).

The penetration and the perforation process of configuration 2 is recorded using HSC 2. It is shown that at the moment of impact, the FSP causes a localized bulge at the rear side of the plate. A localized shearing of material, induced by the FSP front surface, is created in the contact zone. Immediately after, the FSP penetrates and a circular plug is punched through the plate, leaving a clean cut hole. Subsequently, the punched plug can be seen attached to the front surface of the projectile. After that, the punched plug is separated from the FSP.
