| Sumario: | This paper shows an introduction to fatigue crack growth under variable amplitude loading. Sorne methods to predict the fatigue crack growth under variable amplitude loading in metals are brietly described. First of all it is analysed a very important aspect that makes different the fatigue crack growth in metals under variable amplitude Joading. It is the sequence effect. attention is paid to crack closure and its effect fatigue crack growth. Sorne numerical models to simulale the sequence effect are also considered. Finally, some methods to analyse the fatigue crack growth under irregular and random loading, either cycle or global statistical methods, are described. |
