The present work deals with the optimal placement of piezoelectric actuators on a thin plate using Modified Control Matrix and Singular Value Decomposition (MCSVD) approach. The problem has been formulated using the finite element method using ten piezoelectric actuators on simply supported plate to suppress first six modes. The sizes of ten actuators are combined to outline one actuator by add...

Methods in detecting damages in structural components and monitoring their health is on the way to develop in today’s technology. Approaches; nondestructive towards the part or with the lowest risk; which locate the damage and even diagnose its size, are accentuating the importance of smart materials. One of these materials are piezoelectric that is used both as transducers and actuators in res...

the levy-type analytical solution is employed for the problem of bending of cross-ply and antisymmetric angle-ply piezoelectric hybrid laminated plates with at least two simply supported opposite edges. the governing equations of equilibrium are derived in the framework of the first-order shear deformation plate theory. the equations are classified according to the crystallography type of piezo...

In this paper, the first and second order approximations of Taylor expansion are used for calculating the change of each natural frequency by modifying an arbitrary parameter of a system with a known amount and based on this approximation, the inverse eigenvalue problem is transformed to a solvable algebraic equation. The finite element formulation, based on the classical laminated plate theory...

Piezoelectric principles are widely used to harvest energy in the process of vibrating piezoelectric mass. Different design configurations were studied in the research papers listed. A novel dynamic method of Lead Zirconate Titanate Sensor (PZT) to obtain d33 suitable for the MEMS applications is designed, simulated and analysed results were compared with the fabricated sensor. The Lead Zircona...

The thermoelectroelastic solution for an elliptic piezoelectric inclusion embedded in an in®nite matrix and its application to crack±inclusion problems are investigated in this paper. By combining the method of Stroh's formalism, the technique of conformal mapping, the concept of perturbation and the method of analytical continuation, a general analytical thermoelectroelastic solution for an el...

In this article, we are interested in the behavior of a three-dimensional model periodic perforated piezoelectric plate, when thickness h plate and size ε holes small. We study dependence displacements electric potential on ε, give equivalent limits tend towards zero. compute analytical formulae for all effective properties plate.

Surface acoustic waves (Rayleigh waves) are analyzed for semi-infinite anisotropic solids only for essential propagation characteristics like the velocity and decaying parameters, which are important in engineering applications. The limitations of these results are obvious because devices are usually built on a finite piezoelectric substrate with propagation properties different from the analyt...
