Effect of strain on the interlayer friction behavior of double- walled carbon nanotubes with abnormal interlayer distances

Xi'an Gongcheng Daxue xuebao
In order to reveal the friction mechanism of low-dimensional nanomaterials, and effectively regulate the friction process, the interlayer friction of coaxial double-walled carbon nanotubes (DWNTs) with different interlayer distances under axial tension ...

On the Simulation of the Micro-Contact of Rough Surfaces Using the Example of Wet Friction Clutch Materials

Lubricants, 2019
Friction behavior in a sliding contact is strongly influenced by the surface topography of the bodies in contact. This also applies to friction clutches. Even small differences in surface topography may cause significant differences in friction behavior.

Behavior of Sand Particles in Sand-Steel Friction

Soils and Foundations, 1988
ABSTRACT This paper describes a method for observing the particle behavior near the interface in sand-steel friction tests. A friction testing apparatus was modified to allow the observation of sand particles. Close-up photographs were taken of the sand particles at specified timing in sand-steel friction tests.

Validation of Friction Model Parameters Identified Using the IHB Method Using Finite Element Method

Shock and Vibration, 2019
A hybrid friction model was recently developed by Azizian and Mureithi (2013) to simulate the friction behavior of tube-support interaction. However, identification and validation of the model parameters remains unresolved. In previous work, the friction

Research progress on external friction coefficient test of powders

Fenmo yejin jishu
The external friction behavior between the interface and powders is affected by the properties of the powders, the surface roughness of dies, the relative motion speed, temperature, and pressure. Unreasonable external friction behavior may cause the wear
