Propagation Prediction

Reasonably predicting the fatigue life of specimens, depends on the research and understanding of the fatigue crack propagation behavior under variable amplitude loading (VAL) rather than under constant amplitude loading (CAL). The present study aims at evaluating residual fatigue life under single overload VAL by adopting a dynamical coefficient mechanics (DCM) model which we have reported. New formulas connecting the crack length with number of cycles and expressions for the fatigue crack propagation (FCP) under single overload VAL have been derived and were used to predict crack propagation. The ratios of predicted-to-experimental lives range from 1.00 to 1.09, which indicates that the results obtained from this DCM model are in good agreement with experimental data from published literatures and cover all stages of fatigue crack growth curve.
