Resistivity Versus Compressibility Measurements Techniques for Study of Shock Induced Transition

Abstract

Most of our knowledge about shock induced transformations is derived from measurements of shock and particle velocities produced by well controlled loading. The shock wave techniques involve measurement of shock velocities determined by detecting times of arrival of the wave at two or more stations at known locations. In these experiments arrival times are to be determined within a few nanoseconds to achieve suitable accuracy in the derived shock velocity. Resistivity measurements have been of limited value owing to the complications of the environments. A complete description of these measurement techniques has been given by Graham et al. and fowles. The P.C. apparatus is a used for the measurement of compressibility, resistively, etc. Details of some of these measurement techniques are studies and compared in this present paper.
