review text: The fusion of the probabilistic finite element method and reliability analysis for probabilistic fatigue crack growth is presented. A comprehensive method for determining the probability of fatigue failure for mixed-mode cyclic loading is also presented. The loading is mixed- mode with randomness in the initial and final crack lengths, initial crack angle and position, material properties, crack growth law, crack direction law and loading. The methodology consists of calculating the reliability index via an optimization procedure, which is used to calculate the probability of fatigue failure. Performance of the methodology presented is demonstrated on a classical mode I fatigue problem.
