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.
