Stochastic properties of static friction [PDF]

, 2020
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.

Presenting Static Friction Sensation at Stick-slip Transition using Pseudo-haptic Effect [PDF]

World Haptics Conference, 2019
Previous studies have aimed at creating a simple hardware implementation of surface friction display. In this study, we propose a new method for presenting static frictional sensation using the pseudo-haptic effect as a first attempt, which is the ...

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

Biomimetic 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 ...

Static Friction of Liquid Marbles. [PDF]

Physical Review Letters
Liquid marbles, droplets coated with a granular layer, are highly mobile as particles prevent capillary adhesion to the substrate. Yet their coating creates a static rolling friction, which we measure and model.

Decrease of Static Friction Coefficient with Interface Growth from Single to Multiasperity Contact. [PDF]

Physical Review Letters
The key parameter for describing frictional strength at the onset of sliding is the static friction coefficient. Yet, how the static friction coefficient emerges at the macroscale from contacting asperities at the microscale is still an open problem ...
