“…Unfortunately, the use of these design rules may overestimate the fatigue resistance of very large weldments. At present there is a general acceptance of the fact that, for geometrically similar welds, larger weldments will sustain shorter fatigue lives; and in the U.K., the off-shore structure design codes have recently been modified to reflect this effect of thickness [9].…”

There are four important attributes of weldments which, together with the magnitude of the fluctuating stresses applied, determine their resistance to metallic Fatigue: the ratio of the applied or self-induced axial and bending stresses; the severity of the discontinuity or notch which is an inherent property of the geometry of the joint; the notch-root residual stresses which result from fabrication and subsequent use of the weldment; and the mechanical properties of the notch-root material in which fatigue crack initiation and growth takes place. A simple version of a more elaborate analytical model of the fatigue behavior of weldments [l] is presented here which provides analytical and graphical design aids for design.
