| Abstract: | This paper analyses and simulates the propagation rate of fatigue crack by means of Monte Carlo method, and determines distribution regular and correlation of the parameters in the formula. The simulation results of Monte Carlo method are shown to be rational and reliable by comparing compution data with test data. |
