Dynamic Failure Mechanism of Rock Mass Using Smoothed Particle Hydrodynamics

摘要：

　　The paper presents a numerical procedure based on SPH framework to analyze the fracture and fragmentation process of rock medium under dynamic stress wave followed by gas expansion.To analyze the dynamic fracture mechanism related to blast-induced shock wave and gas expansion,a rectangular rock mass containing multiple blast holes were numerically blasted in the proposed SPH framework.The damage pattern around the boreholes and formations are mainly generated due to tensile cracks and are simulated using the developed numerical tool.It is found that the developed procedure has the potential to provide valuable information to understand the physical phenomena those occur in the failure process of rock mass under blast induced dynamic loads.
