摘要：An acoustic emissions testing device includes a pressurizable chamber, a rocksample, and one or ore acoustic sensors communicably coupled to the rock sample. The
chamber includes a first chamber being pressurizable to a first pressure and a secondchamber pressurizable to a second pressure. The rock sample is positioned within thepressurizable chamber such that a first portion of the sample is exposed to the firstpressure and a second portion of the sample is exposed to the second pressure. Thesecond pressure is increased to a threshold pressure, maintained at the thresholdpressure for a time period, and then decreased. The acoustic sensors detect one or moreacoustic events occurring within the rock sample. In certain embodiments, one or more ofthe intensity, the spatial location, and the propagating direction for one or more acousticevents are determinable. The system includes the testing device coupled to a recorder.
