The damage model was established based on H-J-C and the tension-compression dynamic damage constitutive model was also considered by taking blasting crater test as the research object. Using the LS-DYNA software, the formation of the blasting crater was studied and the rock dynamic damage characteristics were analyzed based on the construction of the dynamic finite element model. And the numerical results were compared with the test data. The results show that the numerical results of the model are consistent with both theoretical and experimental results. And the characteristic of dynamic dam...
