Development of Primary Fragmentation Separation Distances for Cased Cylindrical Munitions
Abstract
The U. S. Army Engineering and Support Center, Huntsville (USAESCH) is currently engaged in projects which require the detection, removal, and destruction of buried ordnance. During removal and destruction operations, the public and the personnel performing the work must be provided protection from both accidental and intentional explosive detonations. DOD 6055.9-STD, "DoD Ammunition and Explosives Safety Standards," establishes permissible exposures to explosive effects including fragmentation, blast overpressure, thermal effects, ground shock, and noise. For fragmentation from an accidental detonation, the safety standard allows a maximum exposure of one hazardous fragment per 600 square feet where a hazardous fragment is defined as a fragment having an impact energy of 58 foot-pounds or greater. For an intentional detonation, DOD 6055.9-STD requires protection from all fragmentation. The USAESCH, Structural Branch, has developed analytical procedures to calculate minimum fragmentation separation distances from both accidental and intentional detonations. Both procedures satisfy the safety standard and are applicable to cased, cylindrical munitions. In this paper, these analytical procedures are reviewed and discussed. Software is presented by which minimum fragmentation separation distances from accidental detonations can be calculated. Finally, the method validation is reviewed and conclusions are provided.
