This article presents a mathematical continuum model to analyze the free vibration response of cross-ply carbon-nanotube-reinforced composite laminated nanoplates and nanoshells, including microstructure length scale effects. Different shell geometries, such as plate (infinite radii), spherical, cylindrical, hyperbolic-paraboloid elliptical-paraboloid are considered in analysis. By employing Hamilton’s variational principle, equations motion derived based on hyperbolic sine function shear deformation theory. Then, solved analytically using Galerkin approach. Two types material distribution proposed. Higher-order nonlocal strain gradient theory is employed capture influences deformation, parameter (nonlocal) material/microstructurescale (gradient). Temperature-dependent properties considered. The validation proposed presented. Detailed parametric analyses carried out highlight effects carbon nanotubes (CNT) pattern, thickness stretching, geometry plate/shell, boundary conditions, total number layers, parameters, vibrational frequencies CNTRC nanoshells.

This paper presents an analytical solution for free-vibration and stability analyses of hybrid-composite toroidal shells. The considered hybrid material incorporates the composition fibers nanocomposite-reinforced matrix (NCRM) such as carbon nanotubes (CNTs) graphene nanoplatelets (GPLs). governing differential equations are extended based on first-order transverse shear deformation theory (FSDT) solved by employing approximation Fourier series Galerkin method. composite in parametric studies consisted three layers which polymeric reinforced CNTs some GPLs other layers.

In this research, investigations are presented of the free vibration porous laminated rotating circular cylindrical shells based on Love’s shell theory with simply supported boundary conditions. The equilibrium equations for obtained using Hamilton’s principle. Also, Navier’s solution is used to solve due results compared previous other researchers. numerical result study indicates that increase porosity coefficient nondimensional backward and forward frequency decreased. Then in terms effects coefficients, type, length radius ratio, speed, axial circumferential wave numbers.
