DETERMINATION OF THE SPEED OF SOUND ALONG THE HUGONIOT IN A SHOCKED MATERIAL

Abstract

Two methods were investigated for approximating the speed of sound (using the Hugoniot or a compression ratio factor). Both methods were shown to have a high degree of accuracy at low pressures and correctly predict higher speeds of sound for the higher energy shocked states. The approximations of higher shock pressures diverge progressively greater at higher shock states. A relationship between the partial derivatives of the change in pressure to the change in volume along the Hugoniot to the isentrope was developed. The linear us-up and Mie-Grneisen equations of state were applied to construct a comparison of the computed speeds of sound using copper.
