Method of calculating shear strength of rock mass joint surface considering cyclic shear degradation
Scientific Reports, 2022 When a rock mass shears along a joint surface, the shear resistance is affected by joint surface undulations and friction between the contact regions.

Shear behavior of bedding fault material on the basal layer of DGB landslide
Scientific Reports, 2023 Daguangbao (DGB) Landslide (12 × 108 m3) is the largest landslide triggered by the 2008 Ms8.0 Wenchuan Earthquake, in which basal shear failure develops on an interlayer fault at 400 m deep under the ground.

Start-up shear of spherocylinder packings: Effect of friction [PDF]
Physical Review E, 2021 We study the response to shear deformations of packings of long spherocylindrical particles that interact via frictional forces with friction coefficient $μ$. The packings are produced and deformed with the help of molecular dynamics simulations combined with minimization techniques performed on a GPU.

Friction-induced shear thickening: A microscopic perspective [PDF]
EPL (Europhysics Letters), 2016 We develop a microscopic picture of shear thickening in dense suspensions which emphasizes the role of frictional forces, coupling rotational and translational degrees of freedom. Simulations with contact forces and viscous drag only, reveal pronounced shear thickening with a simultaneous increase in contact number and energy dissipation by frictional ...

Shear thickening of dense suspensions: The role of friction [PDF]
Physics of Fluids, 2019 Shear thickening of particle suspensions is caused by a transition between lubricated and frictional contacts between the particles. Using three-dimensional (3D) numerical simulations, we study how the interparticle friction coefficient (μm) influences the effective macroscopic friction coefficient (μ) and hence the microstructure and rheology of dense
