and low efficiency of fatigue tests are bottleneck problem for the anti-fatigue design of metallic materials. For this problem, a theoretical fatigue model is proposed in this study, the possible applications have also been discussed. Specific results would be introduced in two serial papers, in which the first paper focuses on the model building and the applications on fatigue strength prediction......
