文摘

The sensitivity of Lamb waves and SH-waves to changes in elastic properties has been studied in different parts of dispersion curves. We demonstrate methodological peculiarities of using these waves for assessing the anisotropy of sheet iron with regard to the selection of frequency range and wave mode and an allowance for the scale factor of anisotropy. Distinctive features of the suggested technique are presented.
