A generalized probabilistic model is developed for the fatigue life and reliability prediction of structures containing a set of non-interacting cracks. The main point is a comprehensive use of the concept of Poisson random sets throughout all the stages of the analysis. The model includes both initial and newborn cracks and crack-wise defects. Macrocracks initiation is considered as a result of dispersed damage accumulation. Inspection, repair and replacement of structural elements are included into the consideration also. The resuts may be interpreted as a fargoing generalization of Weibull distribution [1].
