Abstract
The aim of this paper is to investigate propagating and scattering characteristics of guided wave in the layered plate with defects and to determine whether it is possible to detect, locate and classify the defects by monitoring the echo signals. First, it is considered a two-layered plate consist of steel and aluminum. The guided wave is calculated and analyzed by the transfer matrix and Finite Element Method (FEM) in the layered plate without defects respectively. It is proved the reliability of FEM by the numerical simulation results. Then, FEM is used to simulate the propagation and scattering of the guided wave in the plate. It is found that the size and position of the defect can be obtained by monitoring the reflection coefficient.
