Shock compression and release of polycrystalline magnesium oxide
Creators
Abstract
Release wave profile and Hugoniot equation of state data for low‐porosity polycrystalline MgO are reported to 36 and 133 GPa, respectively. At low pressure, the Hugoniot lies above single‐crystal data, reflecting material strength of 3.1±0.8 GPa. Unloading wave velocities to 27 GPa are consistent with extrapolated compressional sound velocities. The unloading profiles can be fit using a viscoplastic model, but there are significant differences between waveforms for different experimental geometries.
