摘要

Shockless compression experiments were performed on x-cut quartz single crystals to examine the effect of loading path and rate on the inelastic behavior. The Lagrangian wave velocity and stress were determined from the measured particle velocities and compared to the previously measured elastic values. The data show that x-cut quartz remains essentially elastic up to stresses greater than 10 GPa during ramp loading, but that the elastic yield behavior is dependent on the sample thickness. These results indicate that the elastic response of x-cut quartz is dependent on the loading path, rate, and sample thickness.
