Resumo
The modeling of mode I fatigue propagation under complex loading of 2D cracks, which grow in two dimensions changing shape at each cycle, is discussed in this paper. Sequence effects, such as overload-induced crack retardation or arrest are also considered, based on the crack closure idea. A description and a taxonomy of these load interaction models are presented in a companion paper. The numerical implementation of these models is discussed, in particular their application to the ViDa software, developed to automate the fatigue dimensioning process under complex loading by all the traditional methods used in mechanical design.
