The Difficulties of Predicting the Coefficient of Friction in Cold Flat Rolling
Journal of tribology, 2021The flat rolling process is initiated when the frictional forces draw the strip to be rolled into the roll gap. These forces depend on the coefficient of friction, knowledge of which is essential to understand, describe, and analyze the process ...

Finite element analysis of fretting wear considering variable coefficient of friction
Proceedings of the Institution of mechanical engineers. Part J, journal of engineering tribology, 2018Fretting wear is a kind of material damage in contact surfaces caused by microrelative displacement between two bodies. It can change the profile of contact surfaces, resulting in loosening of fasteners or fatigue cracks.

Frictional coefficient during flossing of teeth
Dental Materials, 2018This in-vitro study aimed to develop a technique to measure the frictional forces and determine the frictional coefficient (μ) associated with the rubbing of dental floss against teeth. Incorrect flossing technique and the etiology of grooves at the cementoenamel junction (CEJ) of proximal area of teeth has long been a controversial topic.

Robust Estimation of Road Frictional Coefficient
IEEE Transactions on Control Systems Technology, 2011Vehicle active safety systems stabilize the vehicle by controlling tire forces. They work well only when the commanded tire forces are within the friction limit. Therefore, knowledge of the tire/road friction is important to improve the performance of vehicle active safety systems.
