All fatigue data are present first in terms of nominal stress amplitudes and then re analysed in terms of the mean value of the strain energy density evaluated over a finite size semicircular sector surrounding the tip of the notch. The synthesis permits to obtain a very narrow band characterised by a scatter index equal to 1.96. The synthesis has been carried out with a constant radius independent on the loading conditions.
