    Abstract
  • In order to investigate the mesoscale development in the dynamic fracture damage of heterogeneous rocks at the mineral crystal scale, a heterogeneous rock model that can reflect the microstructure characteristics was constructed based on the particle flow code-grain based model (PFC-GBM) method. By establishing the split Hopkinson pressure bar (SHPB) system using finite difference method FLAC2D and discrete element method PFC2D, the dynamic impact failure process of heterogeneous rock under different impact loading was simulated and studied. Through the self-compiled Fish language, the number of intragranular and intergranular microcracks in different minerals during the dynamic failure process was grouped and counted. The microscopic evolution process of dynamic fracture damage of heterogeneous rocks was deeply analyzed from a mesoscopic perspective. The research results show that intergranular failure is an important reason for the failure of the dominant heterogeneous rock under the static uniaxial compression condition. Under impact loading condition, the growth process of microcracks within and between crystals of each mineral had four stages: initiation, rapid growth, slow growth and stop growth. Similar to the growth pattern of the number of microcracks under static uniaxial compression condition, the number of intergranular cracks at the initial stage of dynamic failure was significantly higher than the number of intragranular cracks in each mineral. The rock mainly suffered intergranular damage. As the degree increases, the number of intragranular cracks in dynamic failure gradually exceeds the number of intergranular cracks. In addition, the peak strain rate and the corresponding maximum pressure as well as the dynamic peak strength and the corresponding maximum pressure under different impact loads in the simulation show good linear relationships, which provides a simple method to quickly determine the relevant dynamic mechanical parameters of the rock.
