What is the fatigue life of a welded joint?

One view is that, because small, sharp, slag intrusions are unavoidably present at the weld toe and act as crack initiation sites, the fatigue life of a welded joint is predominantly controlled by the crack propagation process. [1] See all results for this questionStatistical analysis of fatigue test data - TWIThe offshore environment contains many sources of cyclic loading. Standard design S-N curves, such as those in DNVGL-RP-C203, are usually assigned to ensure a particular design life can be achieved for a particular set of anticipated loading conditions. Girth welds are often the weak link in terms of fatigue strength and so it is important to show that girth welds made using new procedures for new projects that are intended to be used in fatigue sensitive risers or flowlines do indeed have the required fatigue perfoSee more on twi-global fatigue life predictions of welded specimens containingSpot Weld Fatigue Life Prediction by Using Multiaxial fatigue life predictions of welded specimens containingAs per conclusion fatigue life of spot welded joints depends on the stress and strain states around the spot welds.

Prediction of the Fatigue Life of Cast Steel Containing fatigue life predictions of welded specimens containing

comparison between the measured fatigue life of cast steel test specimens containing porosity and inclusions and the fatigue life obtained by modeling the specimen using crack initiation (local stain-life concepts) and LEFM approaches has been presented.[23] In the crack initiation model, the defects were considered to be three-Measurement and Assessment of Fatigue Life of Spot-Weld Accurate and consistent predictions of the model for spot-weld joints in which highly complex stress states develop imply that the model adequately reflects the effects of the basic underlying mechanisms leading to fatigue failure for typical engineering applications.In order to apply the models, which account for fatigue failure only in uniaxially loaded parts, we need to find equivalent stress and strain values Measurement and Assessment of Fatigue Life of Spot them would provide the best predictions for a spot-weld joint. 2 Models for Fatigue Life Prediction Various fatigue life prediction criteria have been suggested in literature.

Jan 01, 1989 · Life predictions of butt welds 1009 Many investigators[7-l 1] thought that FCIL could be neglected in the life prediction of welded elements.
