Abstract
The fatigue analysis of as-welded structures is complicated by the presence of high tensile residual stresses at the weld toe region. Existing guidelines for treating residual stresses tend to be overconservative. For example, in the BSI PD 6493 document the full stress range is used in a fatigue analysis for an alternating tension-to-compression fatigue loading. In this study a simple model was used to represent the effective stress range of an alternating fatigue loading in the presence of the residual stresses. The crack growth behaviour of shallow weld toe cracks was modelled and compared with the experimental result in a fillet welded joint.
