Development and Application of Rock Fracture Propagation Numerical Simulation System
Abstract The mechanism of rock fracture evolution under loading has always been the focus of rock mechanics community. In this paper, to realize the development of rock crack propagation simulation system based on ABAQUS platform, the failure criterions which involve maximum tensile stress criterion, the maximum compressive stress criterion and the Mohr–Coulomb failure criterion (M–C) are programmed into the VUMAT subroutine, and the failure element deletion algorithm is introduced to investigate the deformation and failure process of rock blocks under load. Then, the proposed system is used to analyze the progressive failure process of rock samples under loading. By comparing with the test results, the causes and characteristics of crack expansion are studied, meanwhile the different forms of the rock failure process are explored.
