The aerospace community is currently evaluating a new probabilistic approach to fatigue design of complex components, to support or substitute the deterministic approach that is used in fatigue design. In such a way it will be possible to control the safety/risk level during the aircraft life. For the introduction of this new approach, reliable numerical models for computer codes are necessary to simulate the fatigue phenomenon.
This paper is aimed at describing some numerical models for the evaluation of the early stages of the fatigue life. It will also describe the testing activity carried out to support and validate the models. They will be compared and discussed in respect to the ability of predicting the experimental data.
