Corrosion Cracking of Metallic Materials. Part II. Acoustic Emission - Experiment and Theory.
Abstract
The aspects of acoustic emission associated with the theory of the stress waves emitted from cracking and the experimental measurement of the acoustic emission pulses is reported. In the theoretical phase of the work, a survey of the applicable literature in the area of stress waves from moving cracks is reviewed. Certain simple theoretical arguments pertaining to the energy release from an increment of crack growth are reported. In the experimental phase, an evaluation of a number of ultrasonic nondestructive test transducers for acoustic emission work was carried out and an optimum transducer selected. A complete acoustic emission test system was then constructed and several tests performed by the conclusion of the project. (Author)
