SIMULATION OF COHESIVE CRACK AUTOMATIC PROPAGATION IN CONCRETE STRUCTURES USING SUB-DOMAIN BOUNDARY ELEMENT METHOD

摘要：

Simulation of fracture failure is critical in the integrity assessment of concrete structures. Sub-domain boundary element method is efficient in modelling the cohesive crack automatic propagation. As crack occurs in concrete materials mainly due to its weak tensile strength, maximum principal stress criterion is reasonable in judging the crack propagating direction for concrete structures subjected to tensile stress. Based on sub-domain boundary element method and maximum principal stress criterion, the analysis of cohesive crack automatic propagation in concrete structures is carried out, and the crack propagating path is then obtained from the above method.
