Propagation of Failure in a Circular Cylinder of Rock Subjected to a Compressive Force.
Abstract
The report describes a study designed to contribute to our understanding of how well an intact rock can be modeled using a theoretical model and laboratory tests of the same model. An elastic-elastoplastic finite element code was used to analyze the failure growth of intact rock specimens subjected to uniaxial compression. Intact rock specimens with the same dimensions, test configurations, and physical properties as the finite element model were tested in the laboratory and examined for failure zones and the propagation of failure. Theoretical and laboratory models show that failure commences in the center of the specimen and propagates upward and outward. The extent to which the failure propagates is partially dependent upon the platen diameter and upon the elastic mismatch between platen and speciman. (Modified author abstract)
