Predicting wear of UHMWPE: Decreasing wear rate following a change in direction [PDF]
Wear, 2011 Abstract Computational tools are emerging as design tools for the development of total joint replacement with improved wear performance. The current wear models of polyethylene assume that wear is linearly proportional to sliding distance; however, it is hypothesized that the wear rate varies and is higher near a change in direction, but diminishes ...

Long-Term Wear Monitoring and Wear Prediction by Means of Wear Models
IFAC Proceedings Volumes, 1994 Abstract A method for monitoring and predicting fouling of heat exchangers by means of longterm wear models is described. To monitor progressive fouling, the dependencies between the poles of a second-order transfer-function, the fouling and the operation point are examined.

Development of a model for predicting worn profile of rail under the mixed slip conditions
Nihon Kikai Gakkai ronbunshu, 2020 Rail wear does not develop in a short term, but it is closely related to crack initiation. Furthermore, there is a possibility that the worn profile of rail influences the curving performance or the running stability.

Computational Wear Prediction of TKR with Flatback Deformity during Gait
Applied Sciences, 2022 Loss of lumbar lordosis in flatback patients leads to changes in the walking mechanism like knee flexion. Such variations in flatback patients are predicted to alter the characteristics of total knee replacement (TKR) contact, so their TKR will show ...
