Effect of electromechanical coupling on static deformations and natural frequencies.
A two-way coupled electromechanical theory is used to study static deformations and free vibrations of a laminated hybrid rectangular plate comprised of either piezoceramic (PZT) layers or patches embedded at arbitrary locations in graphite/epoxy layers. A first-order shear deformation theory is used to develop equations for the plate which are solved by the finite-element method (FEM) using eight-node isoparametric elements. Static deflections and natural frequencies computed with open-circuited PZT layers are found to differ significantly from those of grounded PZT layers.
