— A brief outline of a recently developed model which describes the microstructurally short and the physically short crack periods of fatigue crack growth is presented. A single equation to describe both regimes is discussed and the model applied to data on a medium carbon steel. Good predictions relating to the actual experimental lifetime were achieved. The results are compared with the prediction of fatigue life based on a previously reported two‐equation approach.
