When these data are applied to the formula derived by M. A. Schroedl and C. W. Smith, the stress intensity factor K, can be calculated. Comparing this computed K, with that given by theoretical formula, we have found the error to be within t 5.20%. It is believed that the result of this test has met
G0/ . Since the value of the ledge force can be neglected as compared with the other two forces in (I), we get ~c = [ b / ~( 1 -v 2 ) ] ~2 / K I 2 ( 2 )
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 es
