Abstract:

The effect of earth cover on the far-field fragment density expected from the accidental detonation of stored munitions was estimated by preparing three models of fragment-cover interaction. Comparisons of the theoretical calculations with limited experimental data show that the model wherein the crown of the earth cover does not retard any fragments gives the best agreement. Models for fragment-fragment interaction which effectively account for stack configuration lead to a simplified model for the effective number of munitions contributing to the far-field fragment density. An approximation technique for the rapid calculation of the far-field fragment density was prepared to assist in the ready evaluation of any model. Tentative quantity-distance relationships for four munitions were prepared. Parametric studies of the effect of altered mass distributions and fragment shape were conducted to assess possible differences between accidental detonation source parameters and arena data source parameters.
