An Elevated Temperature Fatigue Crack Model for Stainless Steels

Source

A model has been developed for the prediction of cyclic crack growth rates at different frequencies and has been verified for an austenitic stainless steel at elevated temperature. The model is based on the damage concept, and accounts for the viscoplastic behavior of stainless steels at elevated temperature. The inclusion of a creep component in such a model results in good correlation between the predicted and observed data.
