Predicting Damage Development in Composite Materials Based on Acousto-Ultrasonic Evaluation
The stress wave factor nondestructive evaluation method introduced by Vary et al.1 embodied a number of features, some of which were attractive regarding practical application, and others of major significance regarding material characterization.The technique as originally described for application to fiber reinforced composites allowed for local assessment of mechanical integrity in the direction of service loading, and required only access to one side of the component.
