Programmed Load Fatigue Tests on Notched and Welded Specimens of Al-Zn-Mg Alloys

The report describes constant amplitude and programmed load fatigue tests on notched and welded specimens in two high strength aluminium-zinc- magnesium alloys. It is shown that, with very few exceptions, the hypothesis that sigma(n/N) = 1 consistently underestimates life. For the notched specimens...
