... of bench height to burden ratio on rock fragmentation numerically. Bench blast numerical simulation using hybrid finite-discrete element method (FEM-DEM) approach was conducted. Bonded particle model (BPM) combined with particle blast method (PBM) was used to model the bench blasting simulation. The rock...

... Abstract The original rock quality designation ( RQD ) index has several limitations, such as one-dimensional (1D) direction and a single threshold. For these reasons, a novel RQD calculation method is proposed by using 3D discontinuity network simulation. In this method, a 3D discontinuity...

... Abstract Accurately simulating the compressive and tensile mechanical behavior of rock is one of the challenges faced by numerical simulation. In this paper, the rock's triaxial compression experiment and the Brazilian disk simulation were simulated, and the propagation process of the rock...

... the mechanics of the fault could be simulated using this approach, but the simulation correctly predicted the onset of seismicity and transition to dynamic analysis and at similar seismic magnitudes to observations. In terms of the difference in seismic source parameters between seismic and aseismic fault...

... Abstract Hydraulic fracturing is often used to increase the permeability of tight reservoir rocks. In this paper, a coupled hydro-mechanical module has been developed and coded into the Discontinuous Deformation Analysis (DDA) program to simulate the hydraulic fracturing progress...

The influence of low thermal conductivity of asphalt bridge deck on deicing effect is considered in the model, and the temperature and stress of bridge deck are simulated, and the relevant data results are obtained. The actual heat flux required for deicing...
