Multiscale Structural Mechanics of Rotary Shaft Seals: Numerical Studies and Visual Experiments
Lubricants, 2023 Although rotary shaft seals have been used successfully in many industrial applications for decades, their tribological behavior is still not completely understood.

IOP Conference Series: Materials Science and Engineering, 2014 Interfacial contact mechanisms and the superplastic behaviour of fine-grained high carbon steel during solid-state bonding were investigated. According to the results, typical superplastic deformation occurred at the bonding interface under conditions of superplasticity- causing temperature (T = 1003~1053K), bonding pressure (P = 34~44.3MPa), and ...

Advanced Engineering Materials, EarlyView.The tribological behavior of 100Cr6 steel spheres textured via Vickers microindentation is evaluated under lubricated sliding by varying both dimple size and density. Fine and dense textures significantly reduce friction across all lubrication regimes, while large dimples increase it.

Algebraic multigrid methods for constrained linear systems with applications to contact problems in solid mechanics [PDF]
Numerical Linear Algebra with Applications, 2004 AbstractThis paper develops a general framework for applying algebraic multigrid techniques to constrained systems of linear algebraic equations that arise in applications with discretized PDEs. We discuss constraint coarsening strategies for constructing multigrid coarse grid spaces and several classes of multigrid smoothers for these systems.

Advanced Engineering Materials, EarlyView.This study investigates laser shock peening for enhancing fatigue performance of riveted aerospace aluminum joints. A comparative approach with cold expansion combines fatigue testing and synchrotron X‐ray methods. Integrating mechanical testing with residual stress and strain characterization provides insights into how different treatments affect the ...

Process‐Informed Analysis of As‐Built Metal Additive Surface Features
Advanced Engineering Materials, EarlyView.This article introduces a novel method for feature‐based surface texture characterisation directly incorporating manufacturing variables into the feature extraction workflow. This marks a major step towards identifying process‐specific surface properties and their influence on part function and hence a holistic understanding of process–structure ...
