TLDR
In this paper, the flexural vibrations of composite plates are considered, where piezoelastic layers are used to generate distributed actuation or to perform distributed sensing of strains in the plate.Abstract:
This paper is concerned with flexural vibrations of composite plates, where piezoelastic layers are used to generate distributed actuation or to perform distributed sensing of strains in the plate. Special emphasis is given to the coupling between mechanical, electrical and thermal fields due to the direct piezoelectric effect and the pyroelectric effect. Moderately thick plates are considered, where the influence of shear and rotatory inertia is taken into account according to the kinematic approximations introduced by Mindlin. An equivalent single-layer theory is thus derived for the composite plates. It is shown that coupling can be taken into account by means of effective stiffness parameters and an effective thermal loading. Polygonal plates with simply supported edges are treated in some detail, where quasi-static thermal bending as well as free, forced and actuated vibrations are studied.read more

A review on static and dynamic shape control of structures by piezoelectric actuation
TL;DR: In this paper, a literature review is presented for shape control of structures, where special emphasis is laid upon smart structures with piezoelectric control actuation, such that the displacement field of a structure distorted from its original shape eventually vanishes, or the structure follows some desired field of trajectories.

Efficient modeling of smart piezoelectric composite laminates: a review
TL;DR: Current research issues in the development of efficient analysis models and their efficient numerical implementation for smart piezoelectric laminated structures are discussed and future challenge lies in developing efficient theories capable of predicting the interlaminar transverse shear stresses in hybrid laminates directly from the constitutive equations.

Free vibrations of simply-supported piezoelectric adaptive plates: An exact sandwich formulation
TL;DR: In this article, an exact two-dimensional analytical solution is proposed for the free-vibration analysis of simply-supported piezoelectric adaptive plates, based on an original sandwich formulation that considers layerwise first-order shear-deformation theory and quadratic non-uniform electric potential, with no assumptions on electric field and displacement components.
