DYNAMIC FRACTURE PRESSURE OF QUARTZ

Abstract

The dynamic fracture pressure of quartz when mounted in a simple pressure transducer was measured based on pressure steps with rise times of 0.5 to 1 msec. Maximum measured dynamic fracture pressures were about 4 kbar (52 to 62 kpsi). Both natural and synthetic quartz samples were studied. The apparatus consists of a gas operated pressure vessel which utilizes the stretched stem principle for achieving fast valve opening times.
