Nondestructive testing technique measures densities of transply cracks and used to monitor propagation of such damage in advanced polymer-matrix composite materials. Acousto-ultrasonic measuring apparatus, used to measure stress-wave factors (SWF's) of undamaged specimens and specimens that contained various numbers of transply cracks. Acousto-ultrasonic technique of value in examining damage to material from one surface only.
