The measurement of applied and residual stresses in metals using ultrasonic waves
Abstract
The results of measurements of the stress-induced velocity variations of both longitudinal and shear ultrasonic waves in the megacycle region are quoted for steel, aluminium and copper, and the corresponding third-order elastic constants calculated. The methods of measuring the small velocity changes due to both stress and preferential grain alignment are discussed, and some attempts at separating the two effects so that residual stress can be non-destructively detected are described.
