Interaction of compression shock waves with a plane liquid-solid interface
Abstract
The interaction of a spherical compression shock wave with a plane interface between a liquid and an elastic solid is investigated experimentally. The spherical wave is excited by an optical breakdown produced in the liquid by the emission of a 0.4-J ruby laser (pulse length, 15-20 ns) focused by a spherical mirror placed into a cell with distilled water. Schlieren photographs of the shock waves generated in the liquid and the solid are presented. It is shown that the incident wave has a spherical shape, while the transmitted and reflected waves are distorted and their points of contact with the interface may be located beyond that of the incident wave. An expression is derived for determining the distance between the points of contact between the waves and the interface.
