Abstract
The aim of this study is to investigate the effect of viscoelastic support on the free vibration behavior of nanocomposite plates composed of functionally graded (FG) polymers and reinforced with graphene nanoplatelets (GNPs). A four-variable first shear deformation theory with nonlocal elasticity theory is used. By considering new shape functions, it is possible to explain why the transverse shear stresses and strains are parabolically distributed through the thickness of the plate and vanish at the top and bottom. Four alternative FG reinforcement patterns are used. The Halpin-Tsai model is used to calculate the effective material properties of the nanocomposite plates. Numerical results of nanoplate-FG polymer composite are compared with literature predictions to validate the results. A thorough parametric analysis revealed the influence of some important parameters on the dynamic behaviors of GNPs-reinforced FG polymer composite nanoplates, including nonlocal parameters, weight fraction, and parameters related to the viscoelastic basis.
