Abstract

The effect of stress distribution on fatigue was explained in the previous paper. Here, taking this effect into account, fatigue limits under cyclic tension-compression, cyclic torsion and rotating bending were calculated respectively. The ratio of fatigue limit under torsion to that under bending conforms very closely with experiments. As for the ratio of the limit under tension-compression to that under bending, the calculated value formerly did not conform with experiments in some cases. Now, the effect of stress distribution on fatigue being taken into account, the calculated value conforms with experiment in any case.
