Experimental Study on the Transition between Static and Kinetic Frictions of Steel/Shale Pairs

open access: yesShock 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.

Efficiency of polymer materials in highly loaded systems in the aviation industry

open access: yesAviation, 2023
The static coefficient of friction was calculated on an inclined plane tribological stand. Different specimens and masses loading the system were used during the experiment. Surface-to-surface contact was tested in a pin-on-plate setup.

Stochastic properties of static friction

open access: yesJournal of the Mechanics and Physics of Solids, 2021
The onset of frictional motion is mediated by rupture-like slip fronts, which nucleate locally and propagate eventually along the entire interface causing global sliding. The static friction coefficient is a macroscopic measure of the applied force at this particular instant when the frictional interface loses stability.

The Statistical Characteristics of Static Friction [PDF]

open access: yesInternational Journal of Applied Mechanics, 2018
Friction is one of the fundamental issues in physics, mechanics and material science with many practical applications. However, the understanding of macroscopic friction phenomena from microscopic aspect is still on the way. In this paper, molecular dynamics simulations are performed to investigate the static friction between two planar crystal ...

Motion analysis of passive dynamic walking with a rigorously constraint model: A necessary condition for maintaining period-1 gait

open access: yesBiomimetic Intelligence and Robotics, 2022
The friction force is an important environmental factor that influences dynamic walking. While most of the related works simply assume static friction or Coulomb friction, we use the LuGre friction, which accounts for both static and dynamic effects, to ...
