This paper investigates the optimal placement of piezoelectric actuators for the active vibration attenuation of beams. The governing equation of the beam is achieved by coupled first order shear deformation theory with two node element. The velocity feedback controller is designed and used to calculate the feedback gain and then apply to the beam. In order to search for the optimal placement of the piezoelectric actuators, a new optimization criterion is considered based on the use of genetic algorithm to reduce the displacement output of the beam. The proposed optimization technique has been tested for two boundary conditions configurations; clamped -free and clamped-clamped beam. Numerical examples have been provided to analyze the effectiveness of the proposed technic.

An active method of vibration control of a smart sandwich plate (SSP) using discrete piezoelectric patches is investigated. In order to actively control the SSP vibration, the plate is equipped with three piezoelectric patches that act as actuators. Based on the classical plate theory, a finite element model with the contributions of piezoelectric sensor and actuator patches on the mass and stiffness of the sandwich plate was developed to derive the state space equation. LQR control algorithm is used in order to actively control the SSP vibration. The accuracy of the present model is tested in transient and harmonic loads. The applied piezoelectric actuator provides a damping effect on the SSP vibration. The amplitudes of vibrations and the damping time were significantly reduced when the control is ON.

The studies on vibration frequency as well as loading capacity of slender systems are very important issues in the design process. Integration of smart materials with the host structures allows one to create constructions which are able to adjust to the different conditions. The piezo material belongs to the smart materials group. Application of voltage to the piezoparts leads to induction of forces which can cause prestressing of the host structure. The prestressing with the use of piezoceramic elements is a main subject of this paper. The investigated system constitutes a column which is loaded with the specific load. The specific load is realized by means of specially designed heads what results in divergence or divergence-pseudoflutter type of characteristic curves. The results presented in this paper are concern on comparison of the loading capacity magnitude and vibration frequency of a slender system with and without prestressing. Finally, it will be stated when to use complex system with piezopart or the simplified one without it.
