Experimental Study on the Transition between Static and Kinetic Frictions of Steel/Shale Pairs
Shock and Vibration, 2021 The transition between static and kinetic frictions of steel/shale pairs has been studied. It was found that the coefficient of friction decreased exponentially from static to dynamic friction coefficient with increasing sliding displacement.

Existence of long‐time solutions to dynamic problems of viscoelasticity with rate‐and‐state friction [PDF]
, 2019 We establish existence of global solutions to a dynamic problem of bilateral contact between a rigid surface and a viscoelastic body, subject to rate‐and‐state friction.

DYNAMICAL FRICTION IN CUSPY GALAXIES [PDF]
The Astrophysical Journal, 2014 In this paper we treat the problem of the dynamical friction decay of a massive object moving in an elliptical galaxy with a cuspidal inner distribution of the mass density. We present results obtained by both self-consistent, direct summation, N-body simulations, as well as by a new semi-analytical treatment of dynamical friction valid in such cuspy ...

Wear and friction of composites of an epoxy with boron containing wastes
Polímeros, 2015 Polymer surface coatings provide superior adhesion to substrates, some flexibility and corrosion resistance. On the other hand, 400,000 ton of boron wastes are generated each year.

Behavior of Friction in Pneumatic Cylinders with Different Relative Humidity
Tribology in Industry, 2020 Friction directly affects the motion quality and performance of a pneumatic cylinder system. The frictional behavior of pneumatic cylinder depends on pressure, velocity, diameter, lubrication, and working environment, etc.

DYNAMICAL FRICTION IN CUSPIDAL GALAXIES [PDF]
The Thirteenth Marcel Grossmann Meeting, 2015 Dynamical friction is the process responsible for matter transport toward the inner regions of galaxies in form of massive objects, like intermediate mass black holes, globular clusters and small satellite galaxies. While very bright galaxies show an almost flat luminosity profile in the inner region, fainter ones have, usually, a peaked, cuspidal ...

High friction coefficient of vertically aligned carbon-nanotubes: A molecular dynamics simulation
Carbon Trends, 2021 In this study, we perform non-equilibrium molecular dynamics simulations to study the friction coefficient between two carbon nanotubes grown vertically on two separate graphene layers, which are placed parallel to each other with one set in motion ...

Effect of collagen-induced residual stress on the frictional property of articular cartilage
Biosurface and Biotribology, 2018 Previous findings, such as split-line of the articular cartilage surface and curving of sliced cartilage specimen, would suggest that residual stress is contained in articular cartilage.
