Paper Abstract

A 2D model based on Legendre spectral element method (SEM) of a piezoceramic (PZT) patch coupled with an isotropic plate is developed in details, based on coupled linear piezoelectricity and elastodynamic equations. The simulation results are validated experimentally using a notched aluminum plate with surface bonded PZTs, for both actuation and sensing. Good agreement between simulation and experimental results is demonstrated for the fundamental Lamb modes A0 and S0, for a frequency band up to 0.75 on a 1.54 mm thick plate.
