Experimental and Theoretical Studies of Wave Propagation in Granular, Rock and Porous Media

Abstract

An experimental and theoretical study of wave propagation in granular, rock an porous media is described. The wave propagation is a result of explosive loadings of 50-100 micro seconds duration. Specific wave propagational variables include the wave speed, inter-granular contact forces (local wave amplitude) and wave spreading geometries. The relationship of the media microstructure to these propagational variables has been studied for a variety of granular and porous materials.
