The fatigue strength of 7075-T6 aluminium alloy under combined axial loading and torsion was examined. The S-N relations were correlated with the von Mises criterion for the high cycle region (N f ≥ 10 4 cycles) and with the Tresca criterion for the low cycle region (N f < 10 4 cycles), where N f is the cycles to failure.This transition at N r = 10 4 cycles was related to the occurrence of ...
