Quasi-Static Pressure, Duration, and Impulse for Explosions in Structures

Abstract

Similitude analysis has been used to obtain dimensionless parameters for peak quasi-static pressures, blowdown duration, and specific impulse for blast loading within enclosures. Data from the United States and Europe have been collected and analyzed, and then displayed graphically according to relationships derived from the similitude analysis. Three graphs are presented, along with appropriate curve fits, of the peak quasi-static pressure versus the ratio of charge weight to enclosure volume, the reduced duration versus the reduced pressure, and the reduced specific impulse versus the reduced pressure.
