ANALYSIS OF ACOUSTIC EMISSION WAVEFORMS PRODUCED BY ROCK DURING CONTROLLED FRACTURE PROPAGATION. FRACTURE OF CONCRETE AND ROCK: RECENT DEVELOPMENTS. PAPERS PRESENTED AT THE INTERNATIONAL CONFERENCE, UNIVERSITY OF WALES, COLLEGE OF CARDIFF, SCHOOL OF ENGINEERING, SEPTEMBER 20-22, 1989

An experimental research program, designed to detect acoustic emissions (AE) produced during propagation of discrete Mode I and Mode II fractures in large rock specimens, is underway at the Rock Mechanics Laboratory at The University of Texas at Austin. Equipment developed, analytical techniques used, and continuing work are described in detail. Preliminary results indicate several distinct signal types which are being tied to known mechanisms. Results indicate that very similar signals may be produced by very different rocks, suggesting a similarity of internal mechanism during crack propagation.(A) For the covering abstract of the conference see IRRD 829348.
