Abstract:

This paper documents the numerical modeling of the detonation of a simplified munitions stack, referred to as the donor stack, in a temporary storage area and the subsequent effects on the immediate surroundings of the stack. A plausible configuration of a donor munitions stack, a water barricade, and an acceptor munitions stack was modeled in a two-dimensional 2-D Cartesian hydrocode computation using the CTH hydrodynamics computer code. The donor stack was modeled as an uncased, condensed high-explosive charge with a rectangular cross section. The water barricade has a trapezoidal cross section, and the acceptor stack is a solid rectangle. The loading on and pressures within the barricade were computed, as was the whole-body motion of the barricade. A separate, uncoupled computation was then run with the water barricade, reconstituted into its original shape and translating at the late-time velocity from the first computation, interacting with the acceptor stack. These computations were performed as part of a U.S. Army Research Laboratory ARL study titled Munitions Survivability Technology, sponsored by the U.S. Army Defense Ammunition Logistics Ammolog Activity.
