Abstract

The Top-on ultrasonic method proposed earlier was applied to the rising load K_Iscc testing and the validity was confirmed by comparing the determined K_Iscc values with those measured according to the conventional longtime K_Iscc testing in the same environments. In addition, the influences of loading rate, fatigue precracking stress intensity level, and fracture morphology of fatigue precracked zone on K_Iscc were discussed.
