摘要：
The acoustic emissions are the high frequency waves caused by the sudden release of energy from local points within a loaded rock specimen. In common terms these emissions can be related to the formation of microcracks within the rock structure. As the failure propagation in a brittle rock is very much associated with the formation of microcracks, the study of acoustic emissions has a great potential to understand the phenomenon of failure. The test was conducted on Delhi quartzite which is quite a brittle rock. The yield point of the rock specimen has been found more accurately.
