A Review Study of Nondestructive Test Techniques for Residual Stresses in Aircraft Transparencies.

Abstract

The main objectives of this program are to conduct review studies on candidate nondestructive test techniques for determining residual stresses in aircraft transparencies; identify and recommend nondestructive test techniques having potential for further laboratory development and field use. The program consisted of three primary tasks: a comprehensive general literature review of over 150 publications on holography, x-rays, moire', scattered-light, thermal methods, ultrasonic techniques, acoustic emission, magneto-photoelasticity, integrated photoelasticity, laser diffraction, and eddy current techniques; a detailed literature review on scattered light photoelasticity, ultrasonic technique I based on the Rayleigh surface waves, ultrasonic technique II based on the ultrasonic energy reflection at a liquid-solid interface magneto-photoelasticity, and laser diffraction; detailed review studies on scattered-light techniques and ultrasonic techniques I and II. The studies revealed that the basic principles and experimental procedure of ultrasonic technique I based on Rayleigh surface waves is fairly well developed.
