ESDU 76007:2013

ESDU 76007 gives graphs showing fatigue data, extracted from a
wide range of sources in the literature, plotted as alternating
stress against endurance for specimens tested in the as-welded
condition. Stiffener configurations are symmetrically placed on
either side, or across the top and bottom as flanges, or
asymmetrically placed on one side; in all cases the weld is not
loaded directly. Data are also given for loaded joints either with
symmetric straps or of the egg box type. Lines of 99 per cent
confidence are superimposed on the graphs. The location of failure
is discussed.
