A Tactile Sensor Using Piezoresistive Beams for Detection of the Coefficient of Static Friction [PDF]
Sensors, 2016 This paper reports on a tactile sensor using piezoresistive beams for detection of the coefficient of static friction merely by pressing the sensor against an object. The sensor chip is composed of three pairs of piezoresistive beams arranged in parallel

Static friction coefficient depends on the external pressure and block shape due to precursor slip [PDF]
Scientific Reports, 2023 Amontons’ law states that the maximum static friction force on a solid object is proportional to the loading force and is independent of the apparent contact area.

Stochastic Properties of Static Friction [PDF]
Journal of the Mechanics and Physics of Solids, 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.

Comparison of static friction and surface topography of low friction and conventional TMA orthodontic arch wires: An in-vitro study [PDF]
Saudi Dental Journal, 2021 Background: Arch wire surface characteristics, especially surface roughness and topography, influence the coefficient of friction during sliding. The clinician should be familiar with the properties of orthodontic appliances and materials that could ...

Effect of fractal disorder on static friction in the Tomlinson model [PDF]
, 2010 We propose a modified version of the Tomlinson model for static friction between two chains of beads. We introduce disorder in terms of vacancies in the chain, and distribute the remaining beads in a scale invariant way. For this we utilize a generalized

A Static Friction Model for Unlubricated Contact of Random Rough Surfaces at Micro/Nano Scale [PDF]
Micromachines, 2021 A novel static friction model for the unlubricated contact of random rough surfaces at micro/nano scale is presented. This model is based on the energy dissipation mechanism that states that changes in the potential of the surfaces in contact lead to ...

The dependence of the dry friction threshold on rupture dynamics [PDF]
Physical Review Letters, 2011 The static friction coefficient between two materials is considered to be a material constant. We present experiments demonstrating that the ratio of shear to normal force needed to move contacting blocks can, instead, vary systematically with ...

Relationship between contact size and static friction: An approach for rigid crystalline surfaces [PDF]
Friction, 2020 Relationship between contact size (A) and static friction (f) has been studied for rigid crystalline systems. We built a series of systems with two identical surfaces but different orientations and investigated the effects of the size and shape of the ...
