SHOCK WAVES, DISLOCATIONS, AND THEIR INTERACTIONS,

Abstract

THE EXISTING ACROSCOPIC ELASTIC-PLASTIC THEORY IS DEVELOPED IN A HOPEFULLY SIMPLE MANNER. Those aspects of the theory which are of special im portance to shock propagation in solids, and which relate to the microscopic extension of the theory, are treated in length. The 'hydro dynamic' equations are written in the elastic plastic spirit and should be usable by an experi mentalist regardless of the exact microscopic processes involved. A gross theory is hypothe sized to account for known phenomena associated with the shock loading of solids. In particular it is put forward that dislocations are generated within the region associated with the plastic wave front with the number generated being con trolled by the applied normal stress-strain law for the material in question.
