Most references have assumed that stress amplitude is constant, and the dispersion of structural geometry has been considered or the P-S-N curve of materials has been used for fatigue reliability design [1,2].
Structural materials is 16Mn, V=0.1[7].
For single sampling of stress-time history, as shown in Fig. 2, the coefficient of variation V of distribution function of each variable is equal to 0.1, S-N curve(lgN=a+blgS) of materials with constants a=24.0589,b=-7.8056[6].
