The multiple impacts on a monolithic, semi-infinite steel target of a shaped-charge jet in a particulated state were computer simulated by right circular cylinders, having a diameter of 3 mm and moving initially at 5 kms. The penetration histories of two and six penetrators at separation distances of 0, 10, and 50 mm were computed using the DORF code. In each case, the combined length of the penetrators was 27 mm, thereby, preserving the initial total momentum and total kinetic energy of the system. The effects of the number of penetrators and the distance between the penetrators on the total penetration and final hole profile were determined.
