Point Source Explosion in a Solid

Abstract

This report presents an approximate theory of the growth of a point source explosion in an infinite solid or liquid medium in the range of shock pressure below that required to induce a physical change of phase of the material, and above pressures at which the wave propagation can be considered acoustic. The analysis is based on the characterization of the shock state locus for the material by a general form containing three constants related to the compressibility of the material. Both porous and non-porous solids are considered. Peak shock pressure and arrival time data obtained by machine calculation as functions of shock radius are presented graphically and numerically in dimensionless form for several values of the compressibility constants involved. Methods of deducing values of the constants from compressibility data for particular materials are presented. The results are applicable to estimates of shock attenuation in a variety of blast absorbing or shielding materials.
