Notes:
In this study, fatigue strength of load-carrying cruciform fillet welded joints were evaluatedusing a new method proposed by Yamada, for geometric or structural stress in welded joint, that is,one-millimeter stress below the surface in the direction corresponding to the expected crack path.Validity of the method is verified by analyzing fatigue test results for load-carrying cruciform weldedspecimens has different size of weld toe radius, leg length and plate thickness reported inliterature. Structural stress concentration factor for 1mm below the surface was calculated by finiteelement analysis for each specimen respectively. When compared to the basic fatigue resistance curveoffered by BS7608, the one-millimeter stress method shows conservative evaluation for load-carryingcruciform fillet welded joints
