| Abstract: | In this paper, according to equi-principle between fatigue strength distribution and fatigul life distribution on the P-S-N curve, probability density function of fatigue strength at a pres ciribed life is theoretically established by means of probability density function of fatigue life at a given stress level so that reliability analysis can be sucesfully done at the base of the probability density function of fatigue strength. |
