Thermal–Mechanical Coupling Analysis of Wheel–Rail Sliding Friction under Two-Point Contact Conditions

Lubricants, 2023
The generation of wheel–rail-sliding frictional heat is often accompanied by transverse displacement of a wheel. To study the thermal problem of wheel–rail sliding friction at two-point contact, this paper uses an LM tread wheel and a 60 kg·m−1 rail as ...

Influences of microcontact shape on the state of a frictional interface

Physical Review Research, 2020
The real area of contact of a frictional interface changes rapidly when the normal load is altered, and evolves slowly when the normal load is held constant, aging over time.

A Study of Static and Dynamic Mechanical Behavior of the Substrate in Ultrasonic Consolidation [PDF]

, 2006
A new 2-D FEM model is developed for a fundamental study of the time dependent mechanical behavior of the substrate in ultrasonic consolidation. The simulation shows that for a given vibration condition, the amplitude of contact friction stress and ...

Frictional Heating of Tribological Contacts [PDF]

Journal of Tribology, 1995
Wherever friction occurs, mechanical energy is transformed into heat. The maximum surface temperature associated with this heating can have an important influence on the tribological behavior of the contacting components. For band contacts the partitioning of heat has already been studied extensively; however, for circular and elliptic contacts only ...
