| Abstract: | This paper presents a method to describe the shape changes of three-dimensional surface cracks under constant amplitude fatigue in tension, bending, and their composite loading, the analysis results were discussed with the experimental data. A law for describing the aspect ratio of a surface crack in fatigue under bending loads was also proposed. |
