摘要

This report describes the results of a series of hydrocode computations, each of which modeled a steel flyer plate striking a single munition, either an M2A3 or an M483, in one of two different mounting configurations. One mounting configuration was for the munition to be first struck by the flyer plate and then to subsequently translate and strike a backing plate. The second configuration was to have the munition mounted with a buffer pack in contact on the flyer-plate side and be in initial contact with the backing plate on the opposite side. Some of the computations simulated experiments that were previously performed and reported by the U.S. Army Research Laboratory. Those experiments were not instrumented, so only limited data were produced. The primary purpose of the computations was to compute the pressures that may have occurred in the explosive fill to help explain the various exothermic reactions (or lack thereof) that occurred. Several different flyer-plate velocities were simulated in the computations. A brief discussion of parameters that may be related to ignition by shearing is also included.
