Measurement of Isochoric Pressure-Energy Relations for Porous Materials. Part I. Stress-Matching Technique and Reference Material Results
Abstract
For several years pulsed electron beam machines have been used to rapidly deposit energy in sample materials, and various techniques have been employed to infer the resulting constant volume heating pressure-energy (P-E) relation. In Part I, a new electron beam stress-matching technique is described which provides a more direct measurement of both P and E through the utilization of reference materials having known P-E relations. The P-E characteristics of aluminum (6061-T6), germanium (111), quartz (X-cut), and silicon (polycrystal were measured to 100 cal/g and are presented in Part I. The results of the application of this technique to determine the Gruneisen parameters of four porous materials is given in Part 2.
