Mid- and High-Cycle Fatigue of Welded Joints in Steel Marine Structures: Effective Notch Stress and Total Stress Concept Evaluations

•One fatigue resistance curve has been obtained for all welded joints using the effective notch stress- and the total stress concept.•The most accurate fatigue strength and fatigue life time estimates are obtained using a generalised random fatigue limit model.•A linear approximation of the generalised random fatigue limit model design curve provides a better resistance description than a bi-linear IIW and Eurocode based one.
