Abstract

The present study is an experimental investigation of x-cut quartz under shock loading with particular emphasis on the determination of stress-volume states above the Hugoniot elastic limit. X-cut quartz is of particular interest since the material exhibits an unusually large Hugoniot elastic limit and previous authors1–3 have found evidence for a substantial reduction in shear strength above the Hugoniot elastic limit; this reduction in shear strength is in sharp contrast to the behavior of metals. Because x-cut quartz is piezoelectric, it is possible to utilize electrical response measurements on impact-loaded samples to deduce mechanical properties of interest.
