Abstract
Damage in composite materials has been detected using ultrasonic nondestructive techniques.1–5 These studies were all performed on thin composite samples subjected to either a quasi-static tensile force or a constant amplitude tensile fatigue load. Changes in basic ultrasonic parameters, attenuation or velocity, were used as an indicator of damage. Damage was detected once a sufficient amount was present. Attenuation was observed to be dependent on the frequency of the ultrasonic transducers that provides an indication of the dispersive nature of these materials.
