Abstract
Fatigue test data under bending, torsion, and combined bending and torsion are presented for mean stresses from zero to values which caused substantial yielding . The mean normal stresses in the bending and the torsion tests were corrected for the effect of the non linear distribution of stress result ing from yielding. The effect of stress relaxation at high mean stresses was investigated . The applicability of several theories of failure are compared wit h these t est data. The influence o~ anisotropy, mechanism of crack formation, mean stress and maxi. mum stress are discussed.
