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 ... -
Experimental and numerical study of mooring chain residual stresses and implications for fatigue life
(Peer reviewed; Journal article, 2020)Residual stresses in large mooring chains were measured for the first time in this study. Two measurement techniques were employed (neutron diffraction and hole drilling). Elastic-plastic finite element simulation of the ...
