摘要：

In order to reveal the Lamb wave propagation mechanism, the Lamb wave detection of thin plate structure was investigated numerically. To this end, a finite element model was established and the corresponding boundary conditions, mesh size and time step were set. On this basis, the displacement field was solved and the Lamb wave mode was determined in single plate. Compared with the frequency dispersion curve, the error of numerical results is 1.3%, which proves the validity of the numerical results. In addition, for the bilayer plate, the propagation of the Lamb wave between two mediums could be observed by solving the sound field at different times.
