Full Electromechanical Optimization of Shunted Piezoelectric Patch for Controlling Elastodynamic Waves’ Power Flow

Wave propagation and energy diffusion in smart structures with shunted piezoelectric patches are examined in this study. The dynamic behavior of a structure can be modified through piezoelectric shunts with negative capacitance. This technique is extremely interesting, as it controls the dynamic behavior of the structure in a large frequency range. The effects of this piezoelectric shunt are studied via a wave propagation approach, and energy diffusion properties of specific wave modes in the structure can be obtained. However, for a proper design of the overall structure, a finer analysis of the real-life circuit is required. The aim of the present work is indeed to establish some essential rules that will guide one to choose more suitable design parameters for the actual system.
