On the estimation of fatigue life in notches differentiating the phases of crack initiation and propagation

Over the last three decades, a variety of models have been developed in order to predict the life of components under fatigue. Some of the models are based on the definition of the fatigue process as a combination of the phases of crack initiation and crack propagation, considering component life as...
