PARTICLE MOTIONS NEAR EXPLOSIONS IN HALITE. Final Report
Comparative peak particle velocities and peak displacements were measured for coupled (tamped) and decoupled (by a cavity) explosions of high explosive in halite. Recordings are illustrated of particle velocity vs. time in the salt medium and of pressure vs. time on the cavity wall. Peak particle velocities from tamped shots decrease in amplitude as distance/sup -1/s/sup 65/ over distances equivalent to 40 to 800 ft for 1000 lb of high explosive. Permanent displacements in the region of observation were 0.01 in. or less and therefore were not accurately observable with available measuring apparatus. Decoupling factors observed directly apply only to close-in stations. One method of extrapolating close-in data to compute distant decoupling factors gives numbers ranging from 40 to 100 for these particular experiments. Extrapolation to nuclear explosions still requires calculation or experiment and is not attempted here. (auth)
