| ABSTRACT In this paper, the static and dynamic loading of an intelligent beam structure with distributed piezoelectric actuators has been studied. The structure substrate, made of isotropic material, subjected to axial and transverse mechanical loads as well as electrical load. The actuators layers are made of piezoelectric material of PZT type. The one-dimensional isoperimetric Hermit cubic shape functions and the Lagrange interpolation function are used to formulate the finite element model for the distributed coupled electromechanical behavior. The equation of motion of the structure systems is obtained by using the principle of total potential energy considering the Euler-Bernoulli beam assumptions. The results of the proposed finite element model are compared to the available finite element and analytical results of other investigators, good agreement is generally obtained. | ||||
