Analysis of Lamb Wave Propagation Modes In Adhesive Plates And Signal Processing

摘要：

In this paper, a finite element method was used to investigate the lamb wave propagation in aluminum adhesive joints. Using 2D-FFT to recognize the modes, the simulation results were compared with the theoretical results. The experiment results show that the simulation is accurate and effective. It is approved that the lamb wave propagation is multi-mode and dispersion The method of 2D-FFT can effectively identify the Lamb wave modes, the results of the finite element analysis agree well with the test results and the theoretical results.
