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.

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.

Calculating shear friction using an effective coefficient of friction [PDF]

PCI Journal, 2008
This paper examines the current formulas used for the calculation of the effective coefficient of friction μ e in PCI Design Handbook: Precast and Prestressed Concrete. It is not a commentary on the underlying methodology, but an examination of the original test data compared with these equations.

SKIN FRICTION BETWEEN UNDISTURBED OVER CONSOLIDATED SILTY CLAY SOILS AND CONCRETE

Journal of Engineering
Up to date, in many foundation design problems (especially for piles foundation), the shear strength (skin friction) between soil and construction materials of the foundation was usually estimated or correlated without any direct methods for measurement.
