THE EXISTENCE AND IMPLICATIONS OF CURVATURE IN THE RELATION BETWEEN SHOCK AND PARTICLE VELOCITIES FOR METALS,

Abstract

Evidence is presented for the existence of curvature in the relation between shock velocity (U) and particle velocity (u) for metals. Existing U,u data is fit to an expansion of the form U = Cb + b1u + b2/2 (u sq.) where Cb is the bulk sound speed at zero pressure. The slopes b1 thus calculated are shown to agree well with the slopes (bI) predicted on the basis of low pressure ultrasonic data. In addition, possibility of estimating the U,u relation from low pressure data is demonstrated. (Author)
