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.

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 ...
