چکیده مقاله:

This paper presents the free vibration analysis of functionally graded carbon nanotube-reinforced composite (FG-CNTRC) plates resting on elastic foundation (Winkler and PasternakWinkler and PasternakWinkler and Pasternak Winkler and PasternakWinkler and Pasternak Winkler and PasternakWinkler and Pasternak Winkler and PasternakWinkler and Pasternak Winkler and PasternakWinkler and Pasternak Winkler and Pasternak ) using second order shear deformation plate theory (SSDT). The governing equations and the related boundary conditions are derived using the principal of the minimum total potential energy. The Navier-type solution is used for simply-supported boundary conditions, and exact formulas are proposed for the fundamental frequencies. The material properties of functionally graded carbon nanotube-reinforced composites are assumed to be graded through the thickness direction according to linear distributions of the volume fraction of carbon nanotubes.
