Piezoelectric composites for distributed passive electric control: beam modelling, modal analysis, and experimental implementation

Abstract : This thesis studies composite structures hosting distributed piezoelectric elements. It consists of three major parts dealing with beam modelling, modal analysis, and passive vibration control with electric circuits. Beam modeling analyzes the influence of 3D effects on 1D models of layered beams including thickness-polarized piezoelectric laminae and proposes a corrected Euler-Bernoulli model based on a mixed variational formulation. Modal analysis
studies numerical and experimental methods for the identification of an electromechanical modal model of a stepped beam including multiple piezoelectric segments. These results are applied to the optimization of resistive-inductive electric networks for vibration control through distributed piezoelectric shunting. Each part includes theoretical analysis, numerical works, and experimental validation. In particular, the first experimental implementation of distributed piezoelectric shunting with multi-terminal electric networks is presented.
