Measurements of Combined Pressure-Shear Waves by the Oblique-Parallel Impact Experiment

Abstract:

Measurements of shear wave under shock compression give important information of the shear modulus and strength. We had started the measurements of the combined pressure-shear waves by the oblique parallel-impact experiments on sapphire (α-Al₂O₃ single crystal) in several 10s of GPa region by the electromagnetic-gauge method and inclined-mirror method. The samples used ware c-cut sapphire plates. In this paper, the experimental method and configuration of the system are describes. The result will be presented at the conference.
