description abstract	Fatigue data for 76s-T61 aluminum alloy are presented for several combinations of bending and torsion with both alternating and mean stresses. Special fatigue equipment for these tests is described. Correction for yielding was applied to the mean stresses in the bending and in the torsion fatigue tests. The literature on the effect of combined stress and of mean stress in fatigue is reviewed and the results of the present series are compared with those of various theories. A new notation for state of stress and a new criterion for combined stress fatigue are discussed. A new mode of presentation of combined stress results is described.
