FRICTION BEHAVIOR OF EPOXY FLOOR TILES FILLED BY SAND NANOPARTICLES [PDF]
Journal of the Egyptian Society of Tribology, 2018 Proper selection of floor materials can reduce slip accidents. The present work proposes epoxy floor tiles filled by sand nanoparticles. Friction coefficient and electrostatic charge (ESC) generated from sliding of bare foot, foot wearing socks and ...

Pinning of interfaces by localized dry friction [PDF]
Journal of Differential Equations, 2020 We consider a model for the evolution of an interface in a heterogeneous environment governed by a parabolic equation. The heterogeneity is introduced as obstacles exerting a localized dry friction. Our main result establishes the emergence of a rate-independent hysteresis for suitable randomly distributed obstacles, i.e., interfaces are pinned by the ...

FRICTION COEFFICIENT DISPLAYED BY FOOTWEAR WALKING AGAINST RUBBER FLOORING FITTED BY CYLINDRICAL TREADS [PDF]
Journal of the Egyptian Society of Tribology, 2011 There is an increasing demand to investigate proper solutions for reducing slip and fall accidents. The friction of footwear on floor coverings is responsible of the occurrence of slips and falls.

Dry Friction due to Adsorbed Molecules [PDF]
Physical Review Letters, 2003 Using an adiabatic approximation method, which searches for Tomlinson model-like instabilities for a simple but still realistic model for two crystalline surfaces in the extremely light contact limit, with mobile molecules present at the interface, sliding relative to each other, we are able to account for the virtually universal occurrence of "dry ...

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 ...
