Basic Characteristics of Micro-Fatigue-Cracks on the Unnotched Smooth Specimens
초록
Quantitative analysis have been carried out on the micro-cracks on the surface and into the depth of unnotched smooth mild steel specimen under cyclic stains by rotating bending fatigue tests. Some of the results are; (1) Cracks initiate at the early stage of fatigue life N
