Abstract
The effect of a fatigue crack on the time of flight of an ultrasonic longitudinal wave propagating along the crack surface is examined in conjunction with nondestructive evaluation of the depth of closed cracks. The characteristic behaviour of the time of flight with increasing crack depth has been analysed experimentally in comparison with measurements for artificial notches.
