Hydraulic fracturing network modeling based on peridynamics

•A coupled hydromechanmical hydraulic fracturing model based on the Perdidynamics is established, which can simulate the hydraulic fracturing problem with arbitrary fracture network.•The problem of tracing macro fractures in the PD model is solved.•Failure criterion of rock mass shear failure based...
