✦ Synopsis

Theoretical estimation of fatigue limit of notches under axial push-pull loading was made with an emphasis on the formation of non-propagating crack. A critical notch radius and a critical stress concentration factor were determined so as to distinguish notch fatigue limits with crack initiation and crack non-propagation. Errors in calculating fatigue limit of notches and comparisons between theoretical and experimental results were discussed.

Experiments with preloaded notched members of 2024-T3 aluminum alloy have shown that preloads in a wide range, even including those which create overall yielding, increase the fatigue lives of the members. Evidence suggests that the extended fatigue life is primarily due to the residual compressive

Under the conditions of constant nominal applied stress. increasing notch root radius causes an increase in the number of cycles to initiate a fatigue crack at a notch root. An explanation of the effect is given in terms of the effective stress concentration factor of the notch. Data are presented w
