Blast Diffraction Loading on the Front and Rear Surfaces of a Rectangular Parallelepiped

Abstract

Equations have been fitted to shock tube data to provide a prediction technique for the average pressure loading on the front and rear surfaces of rectangular parallelepipeds. Equations are presented as fitted to the data and also as modified for use in a rigid-body response code. The data fitted were obtained from models exposed in a shock tube and instrumented with pressure gages. Incident shock overpressures ranged from 34.5 to 138 kPa (5 to 20 psi), and both two and three-dimensional configurations were utilized. Comparisons with other shock tube data and with the results of a three-dimensional hydrocode (BAAL) calculation are presented.
