An Approach to Quantifying the Influence of Particle Size Distribution on Buried Blast Loading

Buried charges pose a serious threat to both civilians and military personnel. It is well established that soil properties have large influence on the magnitude variability of loading from explosive blasts in buried conditions. In this study, work has been undertaken improve techniques for processing pressure data discrete measurement apparatus; performed through testing truncation methodologies area integration impulses, accounting particle size distribution (PSD) soils used testing. Two experimental investigated allow comparison between global impulse capture method an area-integration procedure Hopkinson Pressure Bar array. This paper explores area-limiting approach, based distribution, as possible approach derive better representation plate, thus demonstrating spatial over target can be related PSD confining material.
