TORSIONAL FATIGUE AND BENDING FATIGUE OF ELECTROPOLISHED LOW CARBON STEEL SPECIMENS

Fatigue tests showed that the maximum shear stresses in the crack initiation limit (CIL) of torsional fatigue are determined only by the stress gradient independently of the notch depth; when the values of the stress gradient are equal, the maximum shear stress in CIL of torsional fatigue is about 1.2 times that of bending fatigue; the surface states of notch roots after 10 to the 7 powers cycles of the limit stress for crack initiation in torsional fatigue are similar to each other; non-propagation of a crack in torsional notched specimens is different from that in bending notched specimens.
