Abstract:

A method for recording slow crack growth, using a conventional ultrasonic tester and chart recorder, is described. The problems caused by changes in the measuring system over long periods were overcome by relating crack growth to the amplitude difference between the crack reflection and a reference reflection. Some applications of the technique are described. Author
