SIMULATION OF AIRBLAST-INDUCED GROUND MOTIONS Phase 11A

Abstract

The results of the Phase IIA, High-Explosive Simulation Technique (HEST) experiment are presented in the form of reduced data. A comprehensive analysis is not presented, although irregularities in the data are discussed. The experiment simulated air blast loading from a nuclear burst by detonating a contained Primacord matrix over a plan area 88 feet by 100 feet. The peak overpressure was 598 psi, the total impulse 19.25 psi-sec, the total duration was 172 msec, and the shock front velocity was 5640 feet per second. Measurements of free field stress, strain, particle velocity, particle acceleration, time of arrival of the wave front, and long-span displacement were made. These data are presented as plots of peak values and time histories.
