Exploring the roles of roughness, friction and adhesion in discontinuous shear thickening by means of thermo-responsive particles

open access: yesNature Communications, 2021
Dense suspensions of colloidal or granular particles can display pronounced non-Newtonian behaviour, such as discontinuous shear thickening and shear jamming.

Shearing of frictional sphere packings [PDF]

open access: yesEPL (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.

Shear-friction behaviour on smooth interface between high-strength and lightweight concrete

open access: yesMagazine of Concrete Research, 2020
This study presents the results of ongoing research to investigate the shear-friction behaviour of the interface between high-strength (HS) concrete and lightweight (LW) concrete by conducting test...

Shear Thickening and Jamming of Dense Suspensions: The "Roll" of Friction. [PDF]

open access: yesPhysical Review Letters, 2020
Particle-based simulations of discontinuous shear thickening (DST) and shear jamming (SJ) suspensions are used to study the role of stress-activated constraints, with an emphasis on resistance to gearlike rolling.

Pre-Cracked Concrete Shear Strengthened with External CFRP Strips [PDF]

open access: yesJournal of Rehabilitation in Civil Engineering, 2013
In reinforced concrete design, there are situations where transfer of shear across a specific plane needs to be considered. Examples of such situation include corbels, bearing shoes, ledger beam bearing, and a host of connection between precast concrete ...

Experimental Study on the Influence of Slurry Concentration and Standing Time on the Friction Characteristics of a Steel Pipe-Soil Interface

open access: yesApplied 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 ...

Friction by Shear Deformations in Multilayer Graphene [PDF]

open access: yesThe Journal of Physical Chemistry C, 2012
We present accurate calculations of friction in graphene films in configurations simulating the presence of an anchoring substrate. We find that a slider induces both out-of-plane and shear deformations, which increase with the thickness of the supported film.

Effects of relative densities on mechanical characteristics of interface between sand and suction caisson during penetration

open access: yesYantu gongcheng xuebao, 2022
Suction caissons are popular for mooring oil and gas platforms and fixing wind turbines. The penetration resistance is mainly the friction between the inner and outer walls during suction penetration in sand.

Measuring Interparticle Friction of Granules for Micromechanical Modeling

open access: yesEnergies, 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.
