In the reliability design of mechanical structures, the statistical fatigue characteristics of the structural members are the most fundamental data, and a lot of them have been accumulated statistically. Various kinds of standards for statistical fatigue tests and analyses have been reported to represent the fatigue property. Probit and staircase methods have also been recommended for determining the mean and standard deviation of fatigue strength. However, it is difficult to select the best one among those models and techniques. Thus one has to establish a furnished comparative study to evaluate the differences between probit and staircase methods. In this paper, based on these models, the comparative study has been performed through the statistical analysis of the fatigue test data reported by simulation study. An interesting result for considering whether which model is better for the aim of experimental objectives under practical condition such as sample sizes, levels of stress amplitudes, and so on.
