Abstract: The method of
two-dimensional stochastic variables is adopted in statistical
treatment of fatigue loads in this paper, and a two-dimensional
probability distribution of fatigue strength is studied
correspondingly. Based on these, a two-dimensional model of
stress interference in strength is set up. If the factors of
effect on fatigue strength are considered as stochastic
variables, the method taking account of these factors in
two-dimensional model of stress interference in strength is
given, and the model is calculated by the Monte Carlo method.
