Abstract : This report essentially is a correlation of important published reports on the results of mathematical analysis, scale and full scale tests, and accidental incidences of superficial damage which tend to approach a different maximum distance for three main types of conditions, (1) single explosions, (2) a series of explosions, and (3) when in conjunction with either (1) or (2) certain types of weather prevail. The data on the maximum distance of glass damage indicate that the results obtained from controlled tests of separate explosions are in reasonable correlation, whereas the accidental reports of damage outside of Aberdeen Proving Ground and some Ordnance depots in 1945 are at abnormally greater distances. These abnormal distances of blast damage have been correlated by some investigators with certain types of meteorological conditions. It is suggested in this report that the damage at abnormal distances also may be the result of the cumulative normal damage of many explosions. The damage to glass and plaster at relatively large distances from explosions is caused by the blast wave through the atmosphere since it has been proven by extensive quarry blasting that the displacement of ground and residential structures at customary distances from the quarry is no greater than those produced by normal living activities within the structure or ordinary traffic conditions outside. The correlation and extrapolation of the formulas for the quantity-distance tables in this report limits their application to explosions of 1000 lbs. and less. (Author)
