Air-coupled ultrasonic inspection of anisotropic composite plates

Abstract

The present research is a continuation of our work [1], in which a set of analytically-based computer models for the coupled time-harmonic oscillation generated by a given source in acoustic fluid with an immersed anisotropic plate has been developed. This study is focused on the influence of anisotropy of the immersed composite plate on the dispersion characteristics of guided waves (GWs) excited by the incident acoustic beam.
