An Equation of State for Shock in Homogeneous Materials and Comparison to Shock Data

Abstract

An evaluation of hypervelocity impact data for metals, ceramics, ionic, and polymer materials and water as it leads to an equation of state for solids, is presented. The results indicate that for shock induced pressure, the materials behave as if they are in corresponding states, so that a single equation relates pressure to particle velocity for the entire range of materials investigated. The relationship between shock velocity and particle velocity can be represented by a line with a single slope and with an intercept associated with the bulk sound velocity. Comparisons to solid state theory are made which permit a discussion regarding Gruneisen's constant.
