Shear Controls Frictional Aging by Erasing Memory
Physical Review Letters, 2020 We simultaneously measure the static friction and the real area of contact between two solid bodies. These quantities are traditionally considered equivalent, and under static conditions both increase logarithmically in time, a phenomenon coined aging. Here we show that the frictional aging rate is determined by the combination of the aging rate of the

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.

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].

Shear mechanism and shear strength component characteristics of soil-stone mixtures
Yantu gongcheng xuebao, 2019 In order to study the shear mechanism and shear strength component characteristics of soil-rock mixtures, seven groups of graded soil-stone materials are prepared, covering three typical cases of good gradation, uniform particle size and missing ...

On the shear thinning of non-Brownian suspensions: Friction or adhesion?
Journal of Non-Newtonian Fluid Mechanics, 2020 Shear thinning is fundamental to a broad range of particle suspensions, both in nature and in industrial applications. Yet the mechanisms governing it remain unclear.
