Sensitive Ultrasonic NDE of Tightly Closed Small Cracks in Carbon Steel Structures

Abstract:

Article Preview

Nondestructive evaluation of tightly closed small cracks in carbon steel has been investigated under no load conditions. The investigation has been carried out by using a new ultrasonic method of testing, which has the capability of dealing with smaller tight cracks sensitively. Tight closure of small fatigue cracks in carbon steel plates is realized when the measured responses are compared with the calculated responses of the identical open cracks. Highly sensitive characteristic of the present method is verified through the comparison of the results with those obtained by the standard ultrasonic method of testing.
