A parameter-free mechanistic model of the adhesive wear process of rough surfaces in sliding contact [PDF]
J. Mech. Phys. Solids 147, 104238 (2021), 2020 In order to develop predictive wear laws, relevant material parameters and their influence on the wear rate need to be identified. Despite decades of research, there is no agreement on the mathematical form of wear equations and even the simplest models, such as Archard's, contain unpredictable fit parameters.

Workpiece Image-based Tool Wear Classification in Blanking Processes Using Deep Convolutional Neural Networks [PDF]
Production Engineering 16(4) (2022) 481-492, 2021 Blanking processes belong to the most widely used manufacturing techniques due to their economic efficiency. Their economic viability depends to a large extent on the resulting product quality and the associated customer satisfaction as well as on possible downtimes.

Wear Test Combining Simulated Occiusal Wear and Toothbrush Wear
Dental Materials Journal, 2003 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

Data Analysis to Study Sub-threshold Delays Incurred by Tyne and Wear Metro Trains
Urban Rail Transit, 2020 The performance of Tyne and Wear Metro system in the UK is measured on a headway basis, and gaps in service that are 4 min or more in excess of scheduled gaps are investigated and the cause documented.

A criterion for critical junctions in elastic-plastic adhesive wear [PDF]
, 2021 We investigate elastic-plastic adhesive wear via a continuum variational phase-field approach. The model seamlessly captures the transition from perfectly brittle, over quasi-brittle to elastic-plastic wear regimes, as the ductility of the contacting material increases.
