In general, fatigue cracks of metallic materials are initiated at the surface defects such as inclusions, fine flaws, slip bands in individual grains and grain boundaries, and the final failure is caused through the propagation process of these cracks under subsequent cyclic loading. By introducing the probabilistic distribution of the surface defects, the fatigue life distribution of the metallic materials is theoretically derived in this study. Theoretical results obtained here are in good agreement with the trends of the experimental results on the fatigue life distributions in a wide range of the applied stresses.
