A model for the prediction of tooth wear in individuals [PDF]

open access: yesAustralian Dental Journal, 2003
AbstractBackground: Easily applied, age‐specific standards are useful in assisting clinicians to decide whether the extent of tooth wear observed in a given patient at a specific age is acceptable or whether intervention is indicated.Method: A simple method of scoring tooth wear and previously established mathematical relationships between tooth wear ...

Measurement of Wear and Friction Coefficients for the Prediction of Fretting Wear [PDF]

open access: yesJournal of the Korean Society of Tribologists and Lubrication Engineers, 2012
Dept. of Mechanical Engineering, Pukyong National University(Received April 10, 2012; Revised May 2, 2012; Accepted May 4, 2012)Abstract − The prediction of fretting wear is a significant issue for the design of contacting mechanical com-ponents such as flexible couplings and splines, jointed structures and so on.

Long-Term Wear Monitoring and Wear Prediction by Means of Wear Models

open access: yesIFAC 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.

Computational Wear Prediction of TKR with Flatback Deformity during Gait

open access: yesApplied 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 ...

Prediction of casing wear depth and residual strength in highly-deviated wells based on modeling and simulation

open access: yesScience Progress, 2020
Casing wear is a serious problem in highly-deviated wells because serious wear will lead to casing deformation, drilling tool sticking and failure of subsequent operations. The purpose of this paper is to predict casing wear depth and evaluate its effect

Intelligent Prediction of Aeroengine Wear Based on the SVR Optimized by GMPSO

open access: yesApplied Sciences, 2021
In order to predict aeroengine wear accurately and automatically, as a predictor, support vector regression (SVR) was optimized by means of particle swarm optimization (PSO).

Notes regarding the roughness filtering effects on wear predictions [PDF]

open access: yesINCAS Bulletin
Roughness measurements have been part of engineering for many decades. Direct contact scanning, white light and laser devices have been routinely used to provide 2D of 3D roughness data files and various roughness parameters.

Predicting wear of UHMWPE: Decreasing wear rate following a change in direction [PDF]

open access: yesWear, 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 ...

Research on Contact and Wear Characteristics of the Planetary Roller Screw Mechanism with Screw Misalignments

open access: yesLubricants, 2022
Misalignments are unavoidable in most applications of the planetary roller screw mechanism (PRSM) due to many potential causes. However, the effect of screw misalignments on the contact characteristics for the PRSM have not been thoroughly investigated ...
