- 237 Improvement of Fatigue Strength of Circumferential Notched Specimen
抄録
More than 90% of failures of machines and mechanical parts are caused by fatigue. In addition, approximately 90% of the fatigue cracks initiate at a stress concentration part of structural component. Therefore, it is important to improve the fatigue limit of a notched specimen. In this study, the fatigue properties of specimens with circumferential notch have been investigated using Ono-type rotating bending fatigue test machine. The main results obtained in this study are as follows: (1) The fatigue strength of a notched-specimen considerably increases by roller-working. (2) The improvement of fatigue limit by roller-working would be attributed to work-hardening and compressive residual stress. (3) Furthermore, the non-propagating cracks are observed in the specimen subjected to the stress amplitude of fatigue limit by 1 × 10^7 cycles.
