Shock Wave Interaction in Solid Materials

Abstract

Most of the experimental studies on shock wave propagation in condensed media has been directed toward the study of material science by using the extreme conditions realized by shock compression [1–3]. In this sense, the shock wave is regarded as a useful tool of studying materials. Unlike gases or liquids, solid materials have a wide variety of properties, which is usually hard to discuss in a universal manner. The so-called law of corresponding states known for gas and liquid systems does not apply to solids at least in the same sense. One of the exceptional example of universalities in solid materials is the empirical Hugoniot relationship between shock velocity and particle velocity [4]. This fact seems rather curious, considering the wide variety of materials measured. At least within author’s knowledge, the deep physical meaning of this universal law is still unknown. This law naturally comes from the form of equation of state, or from that of constitutive relations for the materials. It also includes much ambiguities, and is one of the major objectives of shock compression experiments.
