摘要

The oretical waves of Lamb waves in plate structures are obtained by theoretical analysis. An elastic mechanical analysis of metallic plate structure in space and wave-number domains, and an electromechanical analysis of metallic of piezoelectric sensors are achieved. Then, a common analytical model of Lamb waves in metallic plate is established. Based on the analytical model, the theoretical waves and amplitude-frequency characteristics of Lamb waves can be obtained. Finally, to validate the modeling results, an experiment of Lamb wave propagation is conducted. Compared the experiment result with the modeling result, the availability of the analytical model is validated.
