The simultaneous impact of multiple shaped-charge jets on a concrete target has been observed experimentally to lead to the formation of a larger and deeper entrance crater than would be expected from the superposition of the craters of the individual jets. The problem has been modeled with the 3-D simulation code ALE3D, running on massively parallel processors. These calculations indicate that the enlarged damage area is the result of tensile stresses caused by the interactions among the pressure waves simultaneously emanating from the three impact sites. This phenomenon has the potential for enhancing the penetration of a follow-on projectile.
