Paper Abstract

Piezoceramic transducers (PZTs) have been successfully employed for electromechanical impedance (EMI) technique based models of structural health monitoring (SHM) in the recent past. In the EMI models, the PZTs are generally surface bonded or embedded inside the host structure, and then subjected to actuation so as to interrogate the structure for the desired frequency range. The interrogation results in the prediction of electro-mechanical (EM) admittance signatures. These EM signatures serve as indicator of the health/integrity of the structure. However to effectively monitor structural health, understanding interaction mechanism of PZT with host structure is essential. Interaction of surface bonded PZT is different from that of an embedded PZT. This paper presents an over view of all the one, two and three dimensional interaction mechanisms considering different actuation of the PZT in the presence of electric field. Additionally it presents the existing single and multiple PZTs and their mathematical relationships.
