Couette shear is the shear of an object between two infinite planes.Compared with direct shear and simple shear test,in Couette shear test,there is no need to set an artificial shear band or boundary
Aiming at the problem that the safety factor calculated by conventional gravity increase method is larger than the strength reduction method,the modified gravity increase method is applied for slope s
Shale is a typical heterogeneous and anisotropic material whose properties are characterized primarily by locally oriented anisotropic clay minerals and naturally formed bedding planes.
This study proposes a micromorphic elasto-plastic continuum model for granular materials based on a micromechanics approach.In this model,a continuum material point is considered as a granular volume
Hydraulic fracturing technology is a key technology in unconventional oil and gas resources exploitation.In this paper,the extended finite element method(XFEM)is used to simulate the interaction betwe
Simultaneous fracturing stimulations of horizontal well have been wildly used in unconventional reservoirs as effective tools for promoting productivity.The propagation of hydraulic fractures is drive
For hydraulic concrete structures,the external dynamic loads,such as strong earthquake,may cause cracking of these structures.The cracking of the structure causes the fluid injecting into the solid me
