A Test of the Acoustic Impedance Model of Blast Wave Transmission

Abstract

The ability of armor to minimize blast wave transmission is key in mitigating blast related injuries. The acoustic impedance model is commonly employed to estimate blast wave transmission of candidate armor materials even though the model assumes semi-infinite material thickness. The applicability of the acoustic impedance model to blast wave transmission through plates has not been experimentally verified. In this study, a 79 mm diameter, oxyacetylene driven shock tube was used to generate a blast-like wave with a peak pressure of 1173 kPa.
