Wear transitions in a wear coefficient model

A Roll Wear Prediction Model in Hot Plate Rolling

In this paper, the wear of work roll in hot plate rolling is introduced and the parameters affecting wear mechanisms in hot strip mill are investigated. In addition, different wear mechanisms in hot rolling and the differences between these mechanisms in different stands are explained. Using the finite element method and the rolling equations, a work roll wear model is proposed. Wear is modeled...

Mapping Rail Wear Regimes and Transitions

Wear test combining simulated occlusal wear and toothbrush wear.

A new wear testing system, which carries out toothbrush wear and simulated occlusal wear tests alternately, was developed. Differences in wear behavior among three modes of wears, combined wear, toothbrush wear and simulated occlusal wear, were investigated using polymethylmethacrylate (PMMA) and two commercial resin composites (Z100, APX). The area of the material loss after each test was meas...

Visualizing Computational Wear with Physical Wear

Wear is an important source of information supporting our tasks in everyday life. This paper presents the idea of using wear as a new visual attribute for visualizing the computational wear of digital objects, which is defined as a set of attributes resulting from the history of user interactions on the digital objects. As a case study to investigate the feasibility of the proposed idea, we suc...

Tool Wear Estimation from Acoustic Emissions: A Model Incorporating Wear-Rate

(CAAR) is a consortium of researchers from six universities working in partnership with Department of Defense laboratories and industry. CAAR is funded by the Office of Naval Research through a 1997 Department of Research Initiative. Abstract Almost all prior work on modelling the dependance of acoustic emissions on tool wear have concentrated on the effect of wear-level on the sound. We give j...
