• A fatigue crack nucleated in the vicinity of the root of a sharp notch first decelerates with increasing crack length, and then becomes non-propagating or begins to accelerate after reaching a minimum propagating rate depending on the applied stress. In this paper, a method to analyze the growth behavior of such a crack is proposed. The length of a non-propagating crack, and the fatigue limits for crack initiation and for fracture from a notch predicted by the method are compared with the fatigue experimental data for center-notched plates of low carbon steel SM41B and good agreement is obtained
