NUMERICAL SIMULATION OF THE ELASTIC-PLASTIC FAILURE PROCESS ON PILLARS
Based on the self-developed Rock Elastic-Plastic Failure Process Analysis code (REPFPA), the failure process of the pillar, from micro crack to macro crack and including unstable failure, is numerically demonstrated. The pillar is assumed to be a non-homogeneous elastic-plastic material. Many numerical tests are carried out, and it is shown that a relationship is developed between the statistical average strength and the ultimate bearing capacity. Macro shear fracture is the main from of cracking resulting from the pillars elastic-plastic failure.
