Friction is a very complicated phenomenon arising at the contact of surfaces. Experiments
indicate a functional dependence upon a large variety of parameters, including sliding …

This article presents an overview of the acoustics of friction by covering friction sounds,
friction-induced vibrations and waves in solids, and descriptions of other frictional …

This work examines how friction coefficients are affected by amplitude of normal vibration at
different frequencies. Variation of friction coefficient with the amplitude of normal vibration is …

Triboelectric nanogenerators (TENGs) are put forward as a state‐of‐the‐art energy‐
scavenging technology for self‐powered electronics, but their severe wear and degradation …

This paper attempts to predict and discuss some of the many challenges facing fundamental
research in tribology over the first half of the new century. This is done in two stages, looking …

Variation of friction coefficient with the variation of frequency of vibration and relative
humidity is investigated experimentally on a mild steel disc. A pin-on-disc apparatus having …

Study of mechanics of friction and the relationship between friction and wear dates back to
the sixteenth century, almost immediately after the invention of Newton's law of motion. It …

In the present research, friction coefficients of aluminum sliding against different pin
materials are investigated and compared. In order to do so, a pin on disc apparatus is …

olein at different load using pin-on-disk machine N. Nuraliza, S. Syahrullail, MH Faizal …

A very important aspect in highly inclined wellbores is the mechanical friction. For extended
reach drilling (ERD) and through tubing extended reach drilling (TTERD) this can be a …
