dc.description.abstractRock fracture mechanics is concerned with the initiation and growth of fractures in the Earth's crust, rock mass and intact rock at scales ranging from microns to kilometers. This includes the initiation of new cracks from the heterogeneous rock fabric; the opening, closing, sliding, and growth of pre-existing cracks under tension and compression. In rocks, the crack tip non-linear process zone is caused by the initiation and propagation of the microcracks in the immediate vicinity of a crack tip and it is described as the crack tip microcracking zone or Fracture Process Zone (FPZ).This research is a numerical study and focuses on behavior of crack tips in a cylindrical intact rock sample under triaxial stress conditions. All simulations are done by using FRANC2D fracture mechanics program. Results obtained with this study show the behavior of FPZ and fracturing of the pre-existing cracks are found dependent on geometry and position of cracks in the specimen. Some fracture mechanics principles such as fracturing modes mode I (tensile) and mixed mode (tensileshear) were considered in this research as well.
