Abstract: The Shock Release Experiments (SRE) platform has been developed to investigate the off-Hugoniot release path of metals that are shocked to high pressure using plate impact on gas-guns. This simple and direct measurement provides a release isentrope of a shocked sample in a single experiment. The release path is determined by measuring the free surface velocity, along with shock velocity, of up to six witness materials of lower impedance. We present the details of the shock release platform, and an example of the release behavior captured with tantalum samples for shock pressures between 18-24.9 GPa. [ABSTRACT FROM AUTHOR]
