Nondestructive and Semidestructive Methods for Residual Stress Measurement

Abstract

The effect of residual stresses on the fatigue life in metallic components has long been recognized. However, the most commonly employed methods for its measurement are destructive or at least partially so. This has led to an active interest in nondestructive methods for residual stress measurement. A review and evaluation has recently been published that describes the essence of the principles of nearly all the applied and proposed methods for nondestructive and semidestructive residual stress measurement. This review is summarized herein.
