Wave propagation in anisotropic plates using trigonometric shear deformation theory

ABSTRACT

In this article, wave propagation in anisotropic rectangular plates based on trigonometric shear deformation theory is studied. To the best of the authors' knowledge, it is the first time that this type of trigonometric plate theory is being used for investigating bulk waves in anisotropic plates. This type of trigonometric theory has only four unknowns but it can model thick plates. To study the accuracy of the present formulations, the authors' results are compared with other papers available in open literature for isotropic plates. Moreover, the influences of different parameters, such as wave number and thickness on the results, are investigated.
