A gradient-based multiaxial criterion for fatigue crack initiation prediction in components with surface roughness
(Journal article, 2018)The current study presents methods to predict the governing crack initiation site and fatigue crack initiation life of components with surface roughness. The surface topography is measured with white light interferometry ... -
Crystal plasticity modeling of microstructure influence on fatigue crack initiation in extruded Al6082-T6 with surface irregularities
(Journal article, 2018)The influence of surface roughness and microstructure heterogeneities in the vicinity of macroscopic stress concentrations are investigated by crystal plasticity simulations. It is shown that in the extruded Al6082-T6 alloy ... -
Digital image correlation for continuous mapping of fatigue crack initiation sites on corroded surface from offshore mooring chain
(Peer reviewed; Journal article, 2021)The full-field digital image correlation (DIC) technique was used to identify crack initiation and early crack growth on irregular, corroded surfaces from offshore mooring chain. Finite element analysis was paired with the ... -
Influence of deformation prior to ageing on fatigue behavior of extruded AA6082-T6 profiles
(Peer reviewed; Journal article, 2022)This paper investigates the effect of plastic deformation before artificial ageing on fatigue behavior of extruded AA6082-T6 profiles. As-received, T4-temper materials are pre-deformed at different strains and followed by ... -
On long-term fatigue damage and reliability analysis of gears under wind loads in offshore wind turbine drivetrains
(Journal article; Peer reviewed, 2014)In this paper, a long-term fatigue damage analysis method for gear tooth root bending in wind turbine’s drivetrains is presented. The proposed method is established based on the ISO gear design codes which are basically ... -
Time domain-based gear contact fatigue analysis of a wind turbine drivetrain under dynamic conditions
(Journal article; Peer reviewed, 2013)This paper presents a general approach to predict the contact fatigue life of the gears in the drive-train system of a wind turbine under dynamic conditions. A simplified predictive pitting model that estimates service ...
