A numerical simulation model of the propagation of a microstructually short crack in monotonic creep was proposed. In the model, the distribution of the crack propagation rate caused by the microstructual inhomogeneity was expressed by means of some random variables showing the grain boundary length and the crack propagation rates at the grain boundary triple points and their midway. The cumulative probability of the crack length was calculated using the Monte Carlo Method and the effects of some factors such as the length was between the grain boundary triple points, the initial crack length, the upper bound and the lower bound of crack propagation rates, and the waveform of crack propagation rate between two adjacent triple points were discussed. The lower crack propagation rate and the initial crack length had greater effects on the probability than did the other factors. The cumulative probability of the crack length in the case of continuous crack initiation during creep was also simulated on the basis of the model, and it coincided very well with the experimental results.
