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).

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 ...

Age-related changes to macrophages are detrimental to fracture healing in mice. [PDF]
, 2020 The elderly population suffers from higher rates of complications during fracture healing that result in increased morbidity and mortality. Inflammatory dysregulation is associated with increased age and is a contributing factor to the myriad of age ...

Fracture through cavitation in a metallic glass [PDF]
, 2008 The fracture surfaces of a Zr-based bulk metallic glass exhibit exotic multi-affine isotropic scaling properties. The study of the mismatch between the two facing fracture surfaces as a function of their distance shows that fracture occurs mostly through
