英文摘要	Based on the two-parameter crack growth rate relation, probability density function (PDF) of stress cycle and specific fatigue crack length are deduced using a single random variable. Compare with Monte Carlo Simulation (MCS), the present approach is more convenient. It is found that the velocity dispersion of crack propagation is due to the cyclic stress amplitude while the material parameter C has less influence, which is caused by randomicity of initial crack length.
