The Effect of Friction on Wide Shear Bands [PDF]
Particulate Science and Technology, 2007 Frictional and frictionless granular materials in a split-bottom ring shear cell geometry show wide shear bands under slow, quasi-static deformation. Here, the differences between frictional and frictionless materials are elaborated using discrete element simulations (DEM).

Revealing the frictional transition in shear-thickening suspensions [PDF]
Proceedings of the National Academy of Sciences, 2017 Significance The sudden and severe increase in the viscosity of certain suspensions above an onset stress is one of the most spectacular phenomena observed in complex fluids. This shear thickening, which has major implications for industry, is a long-standing puzzle in soft-matter physics.

Applied Sciences, 2022 In pipe jacking, the continued growth of friction resistance around the pipe may cause problems, such as an insufficient jacking force, soil collapse, and even land subsidence, which seriously endangers the structural safety of the pipe and surrounding ...

Shearing the vacuum - quantum friction [PDF]
Journal of Physics: Condensed Matter, 1997 We consider two perfectly smooth featureless surfaces at T=0, defined only by their respective dielectric functions, separated by a finite distance, and ask the question whether they can experience any friction when sheared parallel to their interface. We find large frictional effects comparable to everyday frictional forces provided that the materials

Shear friction capacity of self-consolidating concrete
Revista IBRACON de Estruturas e Materiais, 2020 An experimental research was developed to evaluate shear transfer in self-consolidating. Three concrete mixes were prepared, one conventional and two self-consolidating, differing on the proportion of the coarse and fine aggregate used.

Measuring Interparticle Friction of Granules for Micromechanical Modeling
Energies, 2022 The aim of this paper is to develop an experimental procedure to measure contact friction between granular particles. The contact friction is a micro-property needed in the micromechanical modeling of a granular medium.

Shearing of frictional sphere packings [PDF]
EPL (Europhysics Letters), 2011 We measure shear response in packings of glass beads by pulling a thin, rough, metal plate vertically through a bed of volume fraction phi, which is set, before the plate is pulled, in the range 0.575 to 0.628. The yield stress is velocity independent over 4 decades and increases exponentially with phi, with a transition at phi approximately 0.595.

Effects of Groove Feature on Shear Behavior of Steel-Sand Interface
Advances in Civil Engineering, 2020 Surface groove morphology of structure and particle distribution of soil had a significant effect on the surface friction of structure. In order to investigate the interface shear stress-shear displacement curves, interface model and interface shear ...
