Abstract
An analysis of guided wave energy propagation in a inhomogeneous multi-layered composite structure is presented. It has earlier been reported that ultrasonic guided wave energy within an inhomogeneous composite materials tend to follow the orientation of the fibers, even when the plane of the incident wave is not along the fiber direction [1–3]. In this paper, an exact analysis of a plane wave incident onto a generally anisotropic, visco-elastic, multi-layered composite structure is use here to study the energy flow behavior of guided ultrasonic waves in inhomogeneous composite plates [4] is used to predict this behavior. The reflected and refracted coefficients are obtained by using the well know Thomson-Haskell transfer matrix method [5] which transfer boundary conditions from one side of a solid medium to the other. Then, the power flow vector is used to study the energy distributions within the plates as well as the generation mechanism of guided waves.
