| Abstract: | The effects of damage on the nonlinear dynamic behavior of damaged viscoelastic laminated plates with a transverse periodic excitation are studied. Using the first order shear deformation theory, Boltzmann superposition principle and Galerkin technique, the nonlinear equations of antisymmetric cross-ply viscoelastic laminated plates with damage are derived. By numerical results, the effects of the damage on nonlinear dynamic behavior of visvoelastic laminated plates are discussed. |
