It was shown in the 2nd report how the fundamental formula is applied to the twodimensional stress, and now in this report, we treat the combination of normal and shear stresses and the computed fatigue limits are shown in terms of σ-τ coodinates as curved lines for each material, compared with experimental results of the combined bending and torsion. In the case where either normal on shear stress is static and the other repeating, the endurance limit of ductile materials, decreases or tends to increase (in some range) with the increase of static stress, the characteristics of which agree with experimental results.
