Fatigue Crack Growth Predictions in Tubular Welded Joints

Part of the Lecture Notes on Coastal and Estuarine Studies book series (COASTAL, volume 12)


The present method of fatigue life prediction for tubular joints is based on stress-life (S/N) curves which are obtained by testing large scale tubular joints and then relating a characteristic stress, known as the hot spot stress (Department of Energy, 1981), to the total number of cycles to failure. It is important, however, to note that these S-N curves are not true S-N curves for the material but ‘fictitious’ S-N curves relevant to the joint geometry. This means that part of the full analysis of the failure mechanism can be omitted, because the data has come from the full scale test.
