Resumen de Some improvements on the energy absorbed in composite plate resting on the viscoelastic substrate
The vibration, as well as energy of a reinforced three-phase hybrid composite plate resting on a viscoelastic foundation subjected to initial stress, is examined with the aid of three-dimensional elasticity theory. The two-parameter viscoelastic Winkler–Pasternak foundation is formulated. The multilayer plate with three, five, and seven layers are modeled with the aid of compatibility conditions. The state-space-based analytical method is utilized as the solution procedure to extract the results. To attain the composite material properties, the rule of the mixture alongside modified Halpin–Tsai model is incorporated. The distribution of the carbon nanotubes is supposed to be nonuniform. The parametric examination on the impacts of the sequence of the composite layers, initial stresses, foundation coefficients, and nanocomposite related constants on the vibration frequency as well as energy stored in the system is carried out. The extracted results indicate that the initial stresses and foundation parameters play a significant role in determining the frequency value along with the energy of the system.
