摘要
The FrostDugdale plot is re-examined and the subject of the non-propagation of fatigue cracks is updated to emphasize that fatigue crack closure is the principal factor responsible for the non-propagation of fatigue cracks which originate at notches. The limitations of the original FrostDugdale plot with respect to notch depth are also discussed.
