Predicting Fragmentation Propagation Probabilities for Ammunition Stacks
Abstract
By combining several existing models, we have developed a tool for estimating probabilities associated with the propagation of detonation, burning, and mechanical damage between ammunition stacks. The models include the FRAGHAZ program for the Monte Carlo treatment of fragment trajectories and the accumulation of hit probabilities. The Jacobs-Roslund criterion for initiation of detonation, and a residual velocity condition for initiation of burning. We have applied this tool to stacks of artillery projectiles and missiles. Since the appropriate fragmentation input data was not always available, notably in the case of missiles, we developed methods of estimating this data. Single artillery projectile donors were shown to require a near-direct hit to initiate detonation in either artillery projectile or missile acceptor stacks. Artillery projectile donor stacks were shown to be much more lethal than missile donor stacks, and missile acceptor stacks were shown to be more vulnerable to the propagation of burning than artillery projectile acceptor stacks.
