An Ultrasonic Technique for Detection of the Onset of Fatigue Damage.

Abstract

The primary purpose of this research was to develop an optimum ultrasonic technique for the early detection of fatigue damage. It is concluded that the optimum ultrasonic technique for early detection of fatigue damage is a technique which permits simultaneous measurements of acoustic emission activity and ultrasonic attenuation changes.
