Abstract

In the present paper, electromechanical finite element modeling of a smart adaptive composite beam is presented. The model is formulated based on linear electromechanics and electro kinematics assumptions. The proposed model is a three layers piezoelectric composite beam that acts as a transverse actuator. The elastic material of the core is isotropic whereas the outer piezoelectric layers are orthotropic. The accuracy of analytic and numerical models is demonstrated by examining the simulation of the two principles of mechanical and electrical energy conservation in a finite element program and also comparing its results with the ANSYS numerical model. In the numerical simulation of the finite element model, there are three mesh including 10, 50, and 100 elements. The parametric simulation consists of three mechanical, electrical, and electromechanical static loading sets. By comparing the results of modeling in the finite element programming and ANSYS, and verifying the principle of electromechanical energy conservation, it can be concluded that the proposed finite element model is efficient and accurate.
