We have been accustomed to traditional materials such as wood, leather, wool... and have known the revolution of plastics and composites materials. Recently, we have known other innovations: these of smart materials able to change the shape as the piezoelectric materials. This work deals with the electro-mechanical modeling of these structures by the finite element method. It consists on to model and to simulate deformations in a square aluminum plate subjected to an electric field. This is achieved by using PZT piezoelectric transducers that have such particularity to deform under the influence of an electric field. The study of the deformed aluminum plates equipped with a PZT patch is considered and these types of materials are commonly used in aeronautics and astronautics, which is the context of our study. We have clearly shown the effect of the electromechanical properties of different piezoelectric materials, the transverse piezoelectric coefficient d31 and the longitudinal piezoelectric coefficient d33 of PZT patch on the final response of the intelligent structure.
