Abstract

Modeling and numerical solution of free vibration problem of annular and annular sector plates with carbon nanotube reinforced (CNTR) composites have been presented. First-order shear deformation theory has been used for modeling of laminated composite and CNTR composite materials. The method of discrete singular convolution (DSC) is used for solution of equations of motion for shells and plate. Verification of the accuracy of the present DSC results is verified by appropriate convergence study and checked with the results available in the open literature for isotropic, laminated and CNTR cases. The influence of volume fraction index, boundary conditions, types of CNTR and geometrical parameters on results have been investigated in details.
