Abstract
The aim of this study is to show the state of the art concerning methods of mechanical analysis available in the literature for evaluating notch root elastoplastic strain. The components of fast breeder reactors are subjected to numerous thermal transients, which can cause fatigue failure. To prevent this from happening, it is necessary to know the local strain range and to use it to estimate the number of cycles to crack initiation. Practical methods have been developed for the calculation of the local strain range, and have led to the drafting of design rules. Direct methods of determining the local strain range of the `inelastic analysis` type have also been described. In conclusion a series of recommendations is made on the applicability and the conservatism of these methods.
