Abstract

A study of the fracture process zone was conducted to gain an understanding of the physics of crack propagation in rock. The nondestructive testing technique of acoustic emissions was utilized to estimate the structure of the inelastic region. Charcoal granite was fractured in the double-edge-notched geometry, and the acoustic emissions were located by least-squares iteration method. The major energy sink in crack propagation in rock seems to be the unbroken ligaments within the macrocrack.
