In the reliability design of mechanical structures, the S-N characteristics of the structural materials are the most fundamental data, and a lot of fatigue data of this type have been accumulated. Many of the S-N fatigue models have been reported to represent the fatigue property and various regression techniques have also been developed. However, it is difficult to select the best one among those models and techniques. Of course, the fatigue model is related to the fatigue mechanism of the material. Thus one has to establish a furnished analytical model to represent actual fatigue behavior. Based on that model, one can analyze the fatigue mechanism through the statistical analysis of the fatigue test data reported by various researchers. An interesting method of such data analysis is included in the MIL Handbook of MIL-HDBK-5G. In this study, a new type of fatigue model and the data regression technique are discussed and developed with the aid of this handbook.
