Acoustoelasticity Using Longitudinal Waves for Residual Stress Evaluation
Residual stresses play an important role in the behavior of structures during machining and under load. Knowledge of these residual stress states allows better and more efficient use of the structures, as well as more accurate predictions of their behavior. In this paper, a new method for nondestructively evaluating complete states of plane residual stress is presented. The basic analytical and experimental procedures are reviewed, and results of estimated residual stresses are compared with numerical predictions.
