title = "Predictions of fatigue life of steel connections under combined actions using boundary element method",
abstract = "The fatigue life of girth weld is always an important issue for subsea pipelines. In this paper the method of numerical modeling was used to study the fatigue behaviors of subsea pipeline steel connections. The analytical models were established using the software of BEASY, which is developed on the basis of the boundary element method of analysis. Combined forces were applied in these models: constant amplitude cyclic mode I load and perpendicular static load. The numerical results were compared with the corresponding experimental results and good agreements were achieved. Their fatigue behaviors were described clearly by the stress intensity factors near crack-tip, the crack propagation rates and the fatigue lives. The effect of perpendicular static load, stress ratio and stress range on fatigue behaviors were evaluated through parametric study.",
