Multiscaling behavior of atomic-scale friction [PDF]
Physical Review E, 2017 The scaling behavior of friction between rough surfaces is a well-known phenomenon. It might be asked whether such a scaling feature also exists for friction at an atomic scale despite the absence of roughness on atomically flat surfaces. Indeed, other types of fluctuations, e.g., thermal and instrumental fluctuations, become appreciable at this length

Negative area-dependent nanoscale friction of annular graphene sheets
AIP Advances, 2022 The influence mechanisms of the contact area on the sliding friction behavior are still not entirely clear, and determining the intrinsic correlation between friction and the contact area at the nanoscale remains a challenge.

Investigation of Programmable Friction with Ionic Liquid Mixtures at the Nano- and Macroscales
Lubricants, 2023 Non-mechanical stimuli are used to directly control or program the friction properties of tribosystems. For this purpose, an ionic liquid is used as a lubricant that affects and controls the friction in the presence of external triggers.

On the velocity‐strengthening behavior of dry friction [PDF]
Journal of Geophysical Research: Solid Earth, 2014 The onset of frictional instabilities, e.g., earthquakes nucleation, is intimately related to velocity‐weakening friction, in which the frictional resistance of interfaces decreases with increasing slip velocity. While this frictional response has been studied extensively, less attention has been given to steady state velocity‐strengthening friction ...

Static Friction in a Cable-Driven Transmission—Modeling and Identification of Load Effects
Lubricants, 2022 Although many friction models have been developed by various researchers over the years, a general model does not exist yet. In this article, we present the work that was developed to identify and propose an empirical model that represents the behavior ...

Experimental investigation of friction behavior in pre-sliding regime for pneumatic cylinder
Vietnam Journal of Mechanics, 2014 Friction always presents in pneumatic cylinders and causes difficulties in controlling position and velocity of pneumatic systems. In order to improve the control performance of the pneumatic systems, it is necessary to fully understand behavior of ...

Experimental study on nonlinear friction behavior of granular flow lubrication
Results in Physics, 2022 Solid granules have good lubrication performance and load-bearing capacity, which has been concerned by researchers. However, the correlation mechanism between lubrication performance and granular medium dynamics is hardly focused on.
