摘要：
The Fourier transform representation for the three-dimensional problem of transmission of a bounded ultrasonic beam from an isotropic to a transversely isotropic half space was numerically evaluated. Features in the distortion of the transmitted beam profiles were observed. Comparisons were made to previously obtained experimentally observed beam profiles from columnar-grain steels which revealed that the observed distortions are likely the result of conditions of transverse isotropy. Typical beam distortion encountered during transmission into a fiber-reinforced composite was also calculated.
