CRACK DEPTH MEASUREMENT WITH SURFACE WAVES

FOUR NON-DESTRUCTIVE METHODS OF ESTIMATING SURFACE CRACK DEPTHS ARE DESCRIBED IN THIS PAPER. THREE ELECTRICAL METHODS, A.C. POTENTIAL DROP, D. C. POTENTIAL DROP AND EDDY CURRENTS ARE WIDELY USED AS IS PULSED ECHO ULTRASONIC FLAW DETECTION. AN ALTERNATIVE METHOD USING ULTRASONIC SURFACE WAVES, WHICH HAS FEATURES IN COMMON WITH A. C.
