Wear-out is a much more intractable subject than stress rupture, if only because of the literally hundreds of different wear processes that can lead to failure. In spite of this, a common approach to all wear mechanisms is highly desirable, otherwise design methodology becomes a never-ending topic. A common approach is certainly the target of this book.

Wear and wear transition modeling of ceramics
Wear, 1996Abstract Wear and wear transitions are the major concerns regarding the tribological application of ceramic materials. The objective of this study is to understand wear and wear transition mechanisms of ceramics with emphasis on wear and wear transition prediction. There are four new findings from this research.

This article presents an overview of probabilistic wear models based on lifetime distributions or stochastic processes and discusses their interest in wear‐dependent reliability modeling and condition‐based maintenance evaluation.

Wear characteristics in a two-body wear test
Dental Materials, 1994A previous report compared spherical steatite (ceramic enamel substitute) abraders with those of natural enamel in a two-body wear test. The wear rates and coefficients of friction of the two abraders against various composites and an amalgam were well correlated although the wear rates were slightly higher with steatite.

Analysis for Wear Behaviors of Oxidative Wear
Tribology Letters, 2011Sliding wear tests were performed for H13 steel and a cast steel under atmospheric conditions of 25, 200, and 400°C. XRD results identify that oxidative wear prevailed for the steels during sliding at 200–400°C. However, the oxidative wear at 200°C presented entirely different wear behaviors from the one at 400°C.

Occlusal wear simulation with the ACTA wear machine
Journal of Dentistry, 1994This paper describes how the clinical conditions in stress bearing areas are thought to be simulated in the ACTA wear machine. The wear types simulated are erosive wear and contact sliding wear in the presence of a third-body medium, consisting of natural food substances. Wear due to surface fatigue may also be studied with the wear machine. Wear rates

A particular alumina–PTFE nanocomposite has distinguished itself with unusually large wear reductions at trace filler loadings. Recent studies have shown that the formation of carboxylic acid end groups in humid environments is a critical part of the ...

The interactions between attrition, abrasion and erosion in tooth wear.
Monographs in Oral Science, 2014Tooth wear is the result of three processes: abrasion (wear produced by interaction between teeth and other materials), attrition (wear through tooth-tooth contact) and erosion (dissolution of hard tissue by acidic substances).

Enamel wear caused by monolithic zirconia crowns after 6 months of clinical use.
Journal of Oral Rehabilitation, 2014The purpose of this study was to evaluate enamel wear caused by monolithic zirconia crowns and to compare this with enamel wear caused by contralateral natural antagonists. Twenty monolithic zirconia crowns were placed in 20 patients requiring full molar

This chapter examines the act of wearing text. It considers how the author teaches the relationship between the-media and collective identity through an experiment during which students reflect on their own media consumption. As 'wearing' and identity are inextricably linked — the act of dressing in the morning is a process of performance; a ...
