✦ Synopsis

We express our appreciation to Dr. Yokobori for his interest in our paper [l] and for bringing to our attention their earlier paper [2] on dislocation dynamics theory for fatigue crack growth. The discussion of our paper centers on two points, namely that the dislocation models in [I] and [2] are essentially the same, except [2] was published earlier, and a more important issue that there should be two requirements to be satisfied before a dislocation can be nucleated at the crack tip. These requirements are the stress and energy which are claimed to providerespectively -the necessary and sufficient conditions for the dislocation generation.
