Brief Outline
The angle of internal friction is a fundamental parameter for defining rock failure criteria, however it remains an empirical measure without a firm physical basis. Using a discrete element modelling (DEM) approach, this project will attempt to establish a physical basis for the angle of internal friction, which exercises a critical control on the failure angles of fractures. Detailed examination of the distribution of stresses, infinitesimal strains and cracks during fracture localisation within DEM materials, will provide a means for testing competing models advocating different controlling factors on the angle of internal friction, including strain compatibility requirements and ordinary (sliding) friction.
