| Abstract: | The paper proposes two sets of specimens in different final cold working methods for determining the fatigue limit by accelerated fatigue test. The reliabitity of this method is appraised. The fatigue limit of material in different reliabilities is caculated by lgNP=ap+bplgs. It was confirmed by experiments that fatigue limit of specimens might be determined according to this method, which has no substantial difference between the values of the fatige limit. |
