Exact three-dimensional solutions of laminated orthotropic piezoelectric rectangular plates featuring interlaminar bonding imperfections modeled by a general spring layer

The bending and free vibration of an imperfectly bonded orthotropic piezoelectric rectangular laminates are investigated using a three-dimensional state-space approach. The plate is assumed to have simple supports only, which enables us to obtain a solution in a completely exact form. A general spring layer is adopted to model the bonding imperfections. The laminated plate that is in a state of cylindrical bending is also considered as a particular case. Numerical results are presented and some particular issues are discussed. (C) 2004 Elsevier Ltd.
