| Abstract: | The dual asymptotic method of dynamic analysis of viscoelastic damping sandwich plate is developed. Based upon assumptions of small deformation and linear elasticity, the finite element formulas of viscoelastic damping sandwich plate, including sandwich element, are developed. Finally, the method is validated through laboratory experiment of sandwich beam. |
