“…incompressible, making it impossible to capture localised effects and displacements through the depth of soft cores [17]. If these effects are important, the present formulation can be easily generalised [18] to include an expansion of the transverse displacement of the core in the thickness direction in Eq. 2.…”

In this paper we present a finite element model for the analysis of active sandwich laminated plates with a viscoelastic core and laminated anisotropic face layers, as well as piezoelectric sensor and actuator layers. The model is formulated using a mixed layerwise approach, by considering a higher order shear deformation theory (HSDT) to represent the displacement field of the viscoelastic core and a first order shear deformation theory (FSDT) for the displacement field of the adjacent laminated anisotropic face layers and exterior piezoelectric layers. The dynamic problem is solved in the frequency domain with viscoelastic frequency dependent material properties for the core. Control laws are also implemented for the piezoelectric sensors and actuators. The model behaviour in dynamics is assessed with the few solutions found in the literature, including experimental data, and a laminated composite active sandwich application is proposed. In this numerical application, velocity feedback control law is implemented for active control, using co-located piezoelectric patch sensors and actuators.

“…Beams/plates embedded with piezoelectric materials are widely used in various intelligent material systems for active control because of the electromechanical-coupling properties. For cases of simple geometric shapes, the two-dimensional 2D and three-dimensional 3D analytical methods that were developed by Benjeddou and Deü 22 , Correia et al 23 , Heyliger and Saravanos 24 , and Ding and Chen 25 are effective in analyzing the free vibrations of piezoelectric-laminated plates and provide clear physical meanings in the analytical and symbolical formulations. For cases of complex geometries, boundary conditions, and loadings, the finite element method FEM is more powerful and versatile than classical solutions.…”

An analytical quadrilateral p element is developed for solving the free vibrations of piezoelectriclaminated plates. The formulations of the displacement and strain fields are based on first-order shear deformation plate theory. The coupling effect between the electrical and stress fields is also considered. The Legendre orthogonal polynomials are used as the element interpolation functions, and the analytical integration technique is adopted. It is found that the present p element method gives high numerical precision results, fast and monotonic convergence rate. In the numerical cases, the effects of the number of hierarchical terms and mesh size on the convergence rate are investigated. Examples of square plates with different displacement and potential boundary conditions are studied. In the comparisons, the solutions of the present element are in good agreement with those obtained from other classical and finite element methods.

“…These structures offer potential benefits in a wide range of engineering applications such as vibration suppression, structural health monitoring and shape control. A great deal of research on the use of Piezoelectric materials as distributed sensors and/or actuators has already been carried out for active vibration control of light weight smart structures during the past decade [1][2][3][4][5][6][7][8][9][10][11]. With the rapid development of modern computer technology, finite element method to solve engineering problems has become the most important tools of numerical analysis, plays an important role in analysis of piezoelectric smart structures and simulation [12].…”

With the increasing size of wind turbine blades, the need for more sophisticated load control techniques has induced the interest for aerodynamic control systems with build-in intelligence on the blades. New structural concepts have emerged where multifunctional materials, exhibiting a strong coupling between its mechanical response and its electrical behaviour, which work as sensors and actuators, are embedded or bonded to composite laminates for high-performance structural applications. The paper aims to provide a way for modeling the adaptive wind turbine blades and analyze its ability for vibration suppress. This study provides a finite element model of the smart blade for wind turbines. Numerical analysis is performed using finite element method, which is used to calculate the time response of the model. The displacement response from the piezoelectric actuator and piezoelectric sensors is obtained to control the vibration. By using this model, an active vibration method which effectively suppresses the vibrations of the smart blade is designed.
