Wear modeling and the third body concept
Wear, 2007Many laws already exist for wear, but few are really predictive. In order to better understand the wear process, classical wear models are compared to the third body concept. This concept emphasizes that particle detachment mechanisms, the flow of these particles inside the contact, and their ejection from the contact have to be considered in order to ...

The role of the third body in the fretting wear of 690 alloy
International Journal of Modern Physics B, 2020In this work, to investigate the role of the third body in the fretting behavior of 690 alloy, the fretting capabilities of 690 alloy against 405 stainless steel have been performed under various experimental conditions. The testing normal force and temperature varied from 10 N to 40 N and from room-temperature (RT) to [Formula: see text]C ...

Third-body wear of highly cross-linked polyethylene in a hip simulator
The Journal of Arthroplasty, 2003The wear performance of a radiation cross-linked melted ultrahigh-molecular-weight polyethylene (UHMWPE) articulating against 28-mm cobalt chrome femoral heads in the presence of third-body particulate debris was investigated in a hip simulator and compared with the wear of conventional UHMWPE.

Third-Body-Wear as a Risk Factor in Joint Endoprosthetics
Key Engineering Materials, 2005It is well known, that wear of the articulation partners of hip joint prostheses affect the long-term durability of the implants in vivo. The wear is dramatically increased if particles in the artificial joint gap act as third body. Those particles can also occur after a fracture of a ceramic component.

Total Hip Arthroplasty with Ceramic-on-Ceramic Bearing Failure from Third-Body Wear
Orthopedics, 2011This article describes a new mechanism of failure of a ceramic-on-ceramic total hip arthroplasty (THA) due to fretting corrosion and failure of the Morse taper. A 46-year-old man with hip osteonecrosis underwent THA in 2006. A ceramic-on-ceramic, un-cemented THA with a titanium femoral component and metal-on-ceramic Morse taper was implanted.

A self-similar model for fretting wear contact with the third body in gross slip
, 2021A continuum mechanics approach is applied to model fretting wear in gross-slip regime with accounting for the third-body layer, which is formed by wear debris trapped within contact interface. The developed modeling framework employs the known concept of

The effect of third bodies on wear and friction at the wheel-rail interface
Proceedings of the Institution of Mechanical Engineers, Part F: Journal of Rail and Rapid Transit, 2021The friction forces between the wheel and rail depend on a number of variables including the third body layer at the wheel–rail interface, the wheel and rail profiles, and the train dynamics. The third body layer significantly influences the damage mechanisms at the wheel-rail interface, especially wear, rolling contact fatigue (RCF), corrugations and

Widening Classical Wear Laws to the Concept of Third Body
World Tribology Congress III, Volume 1, 2005During the second part of the twentieth century, many efforts have been done to model wear. Particularly, Archard proposes in 1953 [1] one of the first wear law, which is often written on the following form: dW/dt=K.P.V(1) with dW/dt the mass of detached particles from the rubbing materials per unit time, P the applied pressure, V the sliding speed and

Third Body Effects in the Wear of Polyamide Materials
World Tribology Congress III, Volume 1, 2005This study deals with the micro-wear mechanisms of polyamide materials under reciprocating sliding conditions. Using the resources of in situ contact visualisation through transparent sapphire counterfaces, third body formation and flow processes have been monitored as a function of the sliding amplitude.
