WebA common approach for quantifying fatigue life is using SN curves, which plot stress versus endurance. In standards such as BS7608 and DNVGL-RP-C203 , welds are grouped based on the direction of applied stress with respect to the weld and the weld geometry. A fatigue “Class” therefore provides designers with information about a specific ...
