Abstract: On the basis of the anisotropic damage theory and piezoelectric theory, the nonlinear governing equations for piezoelectric moderately thick laminated plates with damage subjected to a parametric excitation are derived through applying the energy principle and Lagrange equation. Employing the incremental harmonic balance method, a solution for the nonlinear dynamic stability of the piezoelectric moderately thick laminated plates with damage is obtained. In the numerical examples, the influences of damage parameters and piezoelectricity on the nonlinear dynamic stabilities are discussed and the inherent features about the coupled mechanics and electricity are revealed. A comparison is made with available data.
