Influence of Structural Plane Microscopic Parameters on Direct Shear Strength
Advances in Civil Engineering, 2018 Structural plane is a key factor in controlling the stability of rock mass engineering. To study the influence of structural plane microscopic parameters on direct shear strength, this paper established the direct shear mechanical model of the structural

Performance of two-way hinges in reinforced concrete structures
Magazine of Civil Engineering, 2021 Two-way hinges are frequently practiced in bridge columns aiming to avoid the transfer of bending moment to the foundation. The reduction of the concrete column section over a very small height portion is mainly sufficient to create a hinge like behavior.

Noncontact friction via capillary shear interaction at nanoscale [PDF]
Nature Communications, 2015 AbstractFriction in an ambient condition involves highly nonlinear interactions of capillary force, induced by the capillary-condensed water nanobridges between contact or noncontact asperities of two sliding surfaces. Since the real contact area of sliding solids is much smaller than the apparent contact area, the nanobridges formed on the distant ...

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 $ $. The packings are produced and deformed with the help of molecular dynamics simulations combined with minimization techniques performed on a GPU. We calculate the linear shear modulus $g_\infty$,

Shear jamming in granular experiments without basal friction [PDF]
EPL (Europhysics Letters), 2014 Jammed states of frictional granular systems can be induced by shear strain at densities below the isostatic jamming density ($ _c$). It remains unclear, however, how much friction affects this so-called shear-jamming. Friction appears in two ways in this type of experiment: friction between particles, and friction between particles and the base on ...

Debris-bed friction during glacier sliding with ice–bed separation
Annals of Glaciology, 2019 Theory and experiments indicate that ice–bed separation during glacier slip over 2-D hard beds causes basal shear stress to reach a maximum at a particular slip velocity and decrease at higher velocities.
