An accurate fatigue damage model for welded joints subjected to variable amplitude loading
(Journal article; Peer reviewed, 2017)Researchers in the past have proposed several fatigue damage models to overcome the shortcomings of the commonly used Miner's rule. However, requirements of material parameters or S-N curve modifications restricts their ... -
Applying a machine learning method for cumulative fatigue damage estimation of the IEA 15MW wind turbine with monopile support structures
(Peer reviewed; Journal article, 2023)Offshore support structures are critical for offshore bottom-fixed wind turbines, as they bear nearly all the mass and loading of wind turbine systems. In addition, the support structures are generally subjected to a harsh ... -
Experimental and numerical study of the elastic SCF of tubular joints
(Peer reviewed; Journal article, 2021-07)This paper provides data on stress concentration factors (SCFs) from experimental measurements on cruciform tubular joints of a chord and brace intersection under axial loading. High-fidelity finite element models were ... -
Experimental Investigation of Al-CuMgMn Alloy Developed by Laser Beam Surface Modification for Wear Resistance
(Peer reviewed; Journal article, 2021-04)Laser surface alloying is one of the recent technologies used in the manufacturing sector for improving the surface properties of metals. Aluminum alloys are key materials in the manufacturing sector. This favors their ... -
Fatigue Analysis of Inter-Array Power Cables between Two Floating Offshore Wind Turbines Including a Simplified Method to Estimate Stress Factors
(Peer reviewed; Journal article, 2023-06)The use of floating offshore wind farms for electrical energy supply is expected to rise significantly over the coming years. Suspended inter-array power cables are a new design to connect floating offshore wind turbines ... -
Fatigue life analysis of wheel-rail contacts at railway turnouts using finite element modelling approach
(Peer reviewed; Journal article, 2021)The article deals with wheel-rail contact analysis at railway turnout using a finite element modelling approach. The focus is understanding the wheel-rail contact problems and finding the means of reducing these problems ... -
Fatigue strength degradation of metals in corrosive environments
(Journal article; Peer reviewed, 2017)Structures exposed to aggressive environmental conditions are often subjected to time-dependent loss of coating and loss of material due to corrosion; this causes reduction in the cross-sectional properties of the members, ... -
Implementation of linear, double-linear, and nonlinear fatigue damage accumulation rules for fatigue life prediction of offshore drilling top-drive tie-rods
(Peer reviewed; Journal article, 2019-11)The offshore oil and gas industry has been exposed to major challenges over the last decade, particularly demanding cost cuts and more effective technical solutions. Predictive systems and remaining life assessments for ... -
Mixed-mode I and II fatigue crack growth retardation due to overload: An experimental study
(Peer reviewed; Journal article, 2019-12)Environmental loads acting on structures usually cause fatigue crack propagation under variable amplitude mixed-mode conditions. In order to better estimate the remaining fatigue life, the fatigue crack growth behaviour ... -
A review of fatigue damage detection and measurement techniques
(Peer reviewed; Journal article, 2021-09)A vast amount of research has been carried out towards the goal of quantifying changes related to the fatigue damaging process in materials throughout the fatigue life. However, no recommended practice has been developed ...
