Abstract:Based on the microscopic damage mechanics, the finite element method is applied to investigate theinfluence of the inclined joint on the rock fragmentation under impact loading.The viscous boundary is considered to elimilate the influence of the reflected stress waves from the boundary The result shows the inlcined joints change the direction of crack propagation. The lateral cracks appeare first, and thenthe main cracks tend to propagate to theleft side.
