Fragmentation Hazard Computer Model

Abstract

This model provides a method for establishing the fragment hazard produced by the mass-detonation of ammunition stacks stored in the open. Fragmentation characteristics used as input to the model are derived from small- scale arena tests. In the case of 155mm projectiles, for example, the small- scale test may consist of one or more pallets positioned and detonations yield a representative sample of an entire stack. Hazardous fragmentation is defined by the Explosive Safety Board as follows: (1) Fragment kinetic energy of at least 58 ft-lbs. (2) Hazardous fragment density of at least one fragment per 600 square feet. The hazardous fragment density criterion is equivalent to a hit probability of .01 given that the presented area of a man is six squares feet. The unique feature of the model lies in the fact that a complete trajectory is calculated for each fragment recovered in the small-scale arena tests. This procedure requires a great amount of calculations which are made practical by modern high speed computers.
