An improved hydromechanical model for particle flow simulation of fractures in fluid-saturated rocks

Fracture initiation and propagation in fluid-saturated rocks are controlled by interaction between fluid flow rock deformation. The description of hydromechanical coupling is essential for modeling the fracture process. In this paper, an improved model proposed framework particle simulation method. This provides a better hydraulic properties before after breakage bonds can efficiently describe through porous matrix along fractures. efficiency first assessed comparisons with analytical solutions typical experimental evidences. A series numerical simulations then realized to investigate effects some key parameters such as confining stress, injection rate viscosity on
