Static Strength of Friction-Type High-Strength Bolted T-Stub Connections under Shear and Compression

Applied Sciences, 2020
The friction-type high-strength bolted (FHSB) T-stub connection has been widely used in steel structures, due to their good fatigue resistance and ease of installation.

Experimental discrimination of plowing friction and shear friction

Tribology Letters, 2006
The friction experienced by a hard indenter plowing through a relatively soft material consists of two contributions. The plastic deformation of the soft specimen yields a plowing friction component while the shear forces at the area of contact yield shear friction [1–3].

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 ...

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

, 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 ...

Thermodynamics and kinetics of boundary friction [PDF]

, 2011
A deterministic theory describing the behavior of an ultrathin lubricant film between two atomically-smooth solid surfaces is proposed. For the description of lubricant state the parameter of excess volume arising due to chaotization of solid medium ...

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.
