Ray Propagation Path Analysis of Acousto-Ultrasonic Signals in Composites

  • Harold E. Kautz


It has been established that the stress-wave factor (SWF) calculated from acousto-ultrasonic (AU) signals is sensitive to mechanical properties in composite structures.1–13 In particular, it was shown1 that SWF was sensitive to interlaminar shear strength (ISS) in graphite/epoxy.
