英文摘要This study investigates the mechanical properties of rock material at the grain scale. A multilevel parallel bonded-grain based model (Multi Pb-GBM) is proposed to revel the microstructure of granite. The bonded modes of the samples are classified into three types: intra-grain contacts, inter-grain contacts between the same type of mineral, and inter-grain contacts between two different minerals. The parameters of the model are obtained from calculation tests of the uniaxial compressive strength and the Brazilian tension strength. Then, comprehensive simulations are conducted to examine the dynamic damage evolution of brittle granitic rock. The impact of the mineral distribution mode and the grain size coefficient on the simulated failure mode and rock strength are examined. An intact fracture-monitored system is established based on the fish function, and the behaviors of the microfractures are discussed. The results indicate that Multi Pb-GBM can effectively simulate rock mechanical problems and that it has advantages when simulating typical crystalline rocks.
