Modeling Interactions between Hydraulic and Closed Natural Fractures in Brittle Crystalline Rocks: A Fluid–Solid Coupling Grain-Based Approach for Characterizing Microcracking Behaviors
Activating closed natural fractures (NFs) in hot dry rock (HDR) reservoirs is a critical way to improve fluid conductivity and stimulate production. However, the current hydraulic fracturing simulation technol...

A modeling study of the micro-cracking behavior of brittle crystalline rocks under uniaxial loading considering different scenarios of grain-based models
The grain-based model (GBM) in two-dimensional Particle Flow Code (PFC2D) is widely used to simulate the deformation and brittle failure of crystalline rocks. However, the original GBM consisting of the parall...
