Abstract
An investigation of anisotropy in fatigue, under two different states o~ stress, bending and torsion, was made of two aluminum alloys and a steel. A somewhat similar trend was observed in the variation of the fati gue strengths with orientation relative to the texture, for all three metals. Th~ fatigue strength in bending decreased as the orientation changed from longi tudinal to diagonal to transverse; and the fatigue strengn1 in torsion was nearly constant at all three orientations. The results of the test3 are explainable from the concept that cyclic principal shear is primarily the cause of fatigue but the ability of the anisotropic materials to withstand this action of cyclic shear stress is influenced by the magnitude and the direction of the complementary normal stress acting on planes of principal shear stress.
