    Abstract

    This paper provides a physical interpretation and theoretical basis for acousto-ultrasonic (AU) results, using through-thickness-transverse-resonance (TTTR), Lamb wave theory, and elasticity. Major emphasis is given to building a model of the AU method. The paper begins with a brief introduction to the AU method and experimental results, physical interpretations, associated theory, and comparisons between theory and AU results. Finally, conclusions are presented identifying the modes of wave propagation influencing the AU measurements.
