Abstract
A layer-wise first-order shear deformation theory is adopted to construct a model of three-layer piezoelectric sandwich plates. A finite-element formulation of this model, based on a bilinear quadrangular four-node finite element with thirteen degrees of freedom per node, is developed, and any locking phenomenon is avoided by using a reduced-integration technique. This formulation is adopted in the analysis of the vibration suppression problem of a cantilever steel plate, equipped with two piezoelectric patches placed near its clamped edge.
