Measurement of fracture toughness of copper via constant-load microscratch with a spherical indenter
TL;DR: In this paper, a micro-scratch test was conducted on copper under a spherical probe of radius 105μm and constant applied normal load with the aim of characterizing fracture toughness of copper by sliding technique with a sphere.

Tribology of plastic materials : their characteristics and applications to sliding components
TL;DR: In this article, the authors present a method for improving the lubrication of sliding machine parts using friction, wear, and improvement of lubricity. (Reference are included at the end of each chapter.)
Journal ArticleDOI
Microscratch of copper by a Rockwell C diamond indenter under a constant load
TL;DR: In this article, the authors compared the applicability of scratch-based methodologies to characterize the fracture toughness of soft metallic materials with significant plasticity, and found that the results obtained from the microscratch test are influenced by the data range for analysis.
Journal ArticleDOI
Tribological characterization of a bearing coated with UHMWPE/GNPs nanocomposite coating
TL;DR: Polymer nanocomposite coatings with low friction and high wear resistance are being developed to protect aluminium surfaces against wear and tear during dry and boundary lubrication in this paper.
Journal ArticleDOI
Computational method for bearing surface wear prediction in total hip replacements
TL;DR: In this paper, an in-house fretting wear algorithm has been further developed to investigate the wear damage that occurs on bearing surfaces of total hip replacement (THR) and its consequence on the longevity of the implants.

An introduction to the bootstrap
Bradley Efron,Robert Tibshirani +1 more
TL;DR: This article presents bootstrap methods for estimation, using simple arguments, with Minitab macros for implementing these methods, as well as some examples of how these methods could be used for estimation purposes.
Journal ArticleDOI
An Introduction to the Bootstrap
TL;DR: Statistical theory attacks the problem from both ends as discussed by the authors, and provides optimal methods for finding a real signal in a noisy background, and also provides strict checks against the overinterpretation of random patterns.
Journal ArticleDOI
Contact and Rubbing of Flat Surfaces
TL;DR: In this article, the authors compared the deduced dependence of the experimental observables on the load with the experimental evidence and concluded that the most realistic model is one in which increasing the load increases both the number and size of the contact areas.
Journal ArticleDOI
The development of transfer layers and their role in polymer tribology
TL;DR: In this paper, the growth of transfer film with the number of passes is presented and the effect of counterface roughness is examined, and the mechanism of wear is discussed with respect to the transfer film.
