Abstract

[ Fatigue life prediction of real structures is a very complex engineering task. Some of the reasons for which rest on: a) Difficulty or even impossibility of knowing the actual load acting on the structure. b) Existence of sequence effects including retardation and acceleration consequences due to overloads or underloads that can be labelled, in general, as “interaction effects”, which influence the local fatigue crack growth. c) The use of phenomenological, insufficiently founded, and inappropriate cumulative damage models. d) The merely nominal recognition of the random character of the fatigue phenomenon without adopting “de facto” probabilistic approaches. ]
