Nonlinear dynamic response of piezoelastic laminated plates considering damage effects

Based on the Talreja’s damage model with tensor valued internal state variables and the classical geometric nonlinear theory, the constitutive relations of the composite uni-ply plate with damage are derived. Then the nonlinear dynamic equations of the piezoelastic laminated plates considering damage effects are obtained. By using the finite difference method and the Newmark scheme, these equations are solved. Numerical results show the effects of damage and electric loads on the nonlinear dynamic response of the laminated piezoelastic plates.
