Numerical analysis of hydrogen-assisted rolling-contact fatigue of wind turbine bearings [PDF]
Fracture and Structural Integrity, 2014 Offshore wind parks at locations further from the shore often involve serious difficulties, e.g. the maintenance. The bearings of offshore wind turbines are prone to suffer hydrogen-assisted rolling-contact fatigue (HA-RCF).

Evaluation of Fatigue and Fracture Characteristics of High-Speed Rail Material [PDF]
한국정밀공학회지, 2017 Rolling contact fatigue (RCF) and wear caused by rolling contact between the wheel and rail are inevitable problems in railway systems. An increase in axle load or the slip ratio causes excessive wear.

Impact-induced damage accumulation at micro- and nanostructural scale levels in sintered powders SiO2, SiC, and Al2O3 and in their single crystal counterparts [PDF]
Science of Sintering, 2016 The acoustic emission (AE) and fractoluminescence (FL) techniques were applied to study the impact damage in sintered powders of SiO2, SiC and Al2O3 and their single crystal counterparts.

Atomic mechanism of near threshold fatigue crack growth in vacuum
Nature Communications, 2022 It is challenging to understand failure mechanisms under a prolonged low-amplitude loading. Here the authors perform large-scale simulations to better understand the fatigue crack growth mechanism in vacuum, providing an atomic-scale origin for a ...

Fractures in Brief: Olecranon Fractures [PDF]
Clinical Orthopaedics & Related Research, 2012 Olecranon fractures are relatively common injuries, accounting for approximately 10% of upper extremity fractures in adults [26]. These fractures may result from a direct blow to the proximal ulna, or indirectly, via the forceful contraction of the triceps against resistance (typically, during a fall onto an outstretched hand).

Finite Elements in Analysis and Design, 2023 This work introduces “generalized meshes”, a type of meshes suited for the discretization of partial differential equations in non-regular geometries. Generalized meshes extend regular simplicial meshes by allowing for overlapping elements and more flexible adjacency relations.
