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

open access: yesApplied 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

open access: yesScientific 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

open access: yesScientific 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.

Continuum approach to wide shear zones in quasi-static granular matter [PDF]

open access: yes, 2005
Slow and dense granular flows often exhibit narrow shear bands, making them ill-suited for a continuum description. However, smooth granular flows have been shown to occur in specific geometries such as linear shear in the absence of gravity, slow ...

Experimental Study on Interface Frictional Characteristics between Sand and Steel Pipe Jacking

open access: yesApplied Sciences, 2023
In order to study the variation law of shear frictional characteristics of the steel pipe jacking and sand interface under different working conditions, the shear stress–strain curve between five different particle sizes of sand and steel pipe jacking ...

Universality of shear-banding instability and crystallization in sheared granular fluid [PDF]

open access: yes, 2008
The linear stability analysis of an uniform shear flow of granular materials is revisited using several cases of a Navier-Stokes'-level constitutive model in which we incorporate the global equation of states for pressure and thermal conductivity (which ...
