Abstract

[ In the evaluation and prediction of the fatigue lifetime of machines and structures the role of mathematical and statistical models is crucial, due to the high complexity of the fatigue problem, in which the consideration of the stress range, stress level and the size effect, together with an efficient estimation of the corresponding parameters represents one of the most difficult and attracting challenges, which have not yet been satisfactorily solved. As a consequence, reliable failure prediction, engineering design and risk analysis in fatigue are not possible without the help of statistical models. ]
