Rock burst is a kind of severe engineering disaster resulted from dynamic fracture process of rocks. The macro failure behaviors of rocks are primarily formed after experiencing the initiation, propagation, and coalescence of micro-cracks. In this pa

To investigate the effect of an adjacent hole on the blast-induced stress concentration in rock blasting, a rock blasting model with an adjacent hole is explored through theoretical analysis and numerical simulation. The commercial software LS-DYNA i

Rock burst is a multiscale dynamic fracturing process induced by unloading. To further investigate the dynamic fracturing mechanism of rock burst, a grain-based discretized virtual internal bond (GB-DVIB) method is developed. The Voronoi diagram is u

In the coal burst induced by excavation, the burst body is not a closed system because the surrounding rock (the roof and the floor) can work on it. In order to investigate the surrounding rock effect on coal burst caused by unloading, the discretize

Unloading can cause many geotechnical disasters, e.g., the rock burst. The underlying mechanism of rock failure is the propagation and coalescence of cracks. To get insight into rock unloading failure, the discretized virtual internal bond (DVIB) mod

To more accurately simulate the fracture propagation in a quasi-brittle material, a trilinear damage potential is developed, which accounts for both the damage and fracture energy. The bond potential is divided into three stages, namely the linear el
