Abstract

Fracture mechanics plays an important role in studies of geologic materials such as rock and coal. Yet, fracture data are scarce for rock and most limited or unreliable for coal. A testing system was developed which can apply mixed mode loads to a crack tip in many rocks and geologic materials. It is possible to subject the test specimen to pure mode I, various mixed modes and a nearly pure mode II fracture load. The system is currently used to study the mechanics of fine fragment formation in various coals. Experimental measurements include K//I and K//I//I, fracture velocity and acoustic emission.
