Two-dimensional thin plates are widely used in many aerospace and automotiveapplications. Among many methods for the attenuation of vibration of thesemechanical structures, piezoelectric shunt damping is a promising way. Itenables a compact vibration damping method without adding significant mass andvolumetric occupancy. Analyzing the dynamics of these electromechanical systemsrequires precise modeling tools that properly consider the coupling between thepiezoelectric elements and the host structure. This paper presents amethodology for separately shunted piezoelectric patches for achieving higherperformance on vibration attenuation. The Rayleigh-Ritz method is used forperforming the modal analysis and obtaining the frequency response functions ofthe electro-mechanical system. The effectiveness of the method is investigatedfor a broader range of frequencies, and it was shown that separately shuntedpiezoelectric patches are more effective.
