Abstract:Powerful and accurate computation is becoming one of the most important tools for rock failure process analysis and related rock engineering problems. It demands supercomputer or large-scale parallel computer and related software that can be run on them. Common personal computers(PC) and workstations are incapable when they are facing the accurate simulation of micro-scale crack formation and evolution in rocks and other different typs of materials,which requires terascale computing,even petascale super-computing in future. A parallel model of rock failure process analysis is proposed. This model is developed from serial version of rock failure process analysis (RFPA) directly,which has been presented before. Parallelism of finite element method(FEM) in stress module has been completed using discontinuous finite element method and domain decomposition parallel algorithms for parallelization of RFPA. Numerical test shows that the program is robust and possesses good scalability and pocketability. Stress analysis of tens of millions order linear equations has been finished within twenty five minutes on 32-node PC-cluster.
