Shear mechanism and shear strength component characteristics of soil-stone mixtures

Yantu gongcheng xuebao, 2019
In order to study the shear mechanism and shear strength component characteristics of soil-rock mixtures, seven groups of graded soil-stone materials are prepared, covering three typical cases of good gradation, uniform particle size and missing ...

Three-Dimensional Combined Finite-Discrete Element Modeling of Shear Fracture Process in Direct Shearing of Rough Concrete–Rock Joints

Applied Sciences, 2020
A three-dimensional combined finite-discrete element element method (FDEM), parallelized by a general-purpose graphic-processing-unit (GPGPU), was applied to identify the fracture process of rough concrete–rock joints under direct shearing.

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.

Derivation of the Coefficients in the Coulomb Constant Shear Friction Law from Experimental Data on the Extrusion of a Material into V-Shaped Channels with Different Convergence Angles: New Method and Algorithm

Metals, 2022
The combined Coulomb constant shear friction law is widely used in commercial and research software for the finite-element analysis (FEA) of metalworking and is naturally more flexible and hence, more relevant to real-life manufacturing than the ...

Experimental Investigation of the Lubricant Effect of Thixotropic Slurry on Pipe–Soil Interfacial Friction Characteristics

Buildings
Based on the technical issues encountered during underground pipe jacking construction in the Jining area, a series of ring shear tests were conducted on silty clay below the groundwater level to investigate the interfacial friction characteristics under

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.

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 ...

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.
