Abstract:

This paper presents the buckling analysis of functionally graded carbon nanotube-reinforced composite (FG-CNTRC) plates under mechanical loads, 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 buckling analysis. 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. Detailed parametric studies have been carried out to reveal the influences of the WinWinWinkler and kler and kler and kler and kler and kler and Pasternak coefficients Pasternak coefficientsPasternak coefficientsPasternak coefficients Pasternak coefficientsPasternak coefficients Pasternak coefficientsPasternak coefficientsPasternak coefficientsPasternak coefficients Pasternak coefficients Pasternak coefficients and lengthlength lengthlength to thickness ratio on the critical buckling loadthe critical buckling load the critical buckling loadthe critical buckling loadthe critical buckling loadthe critical buckling loadthe critical buckling loadthe critical buckling load the critical buckling loadthe critical buckling loadthe critical buckling load the critical buckling loadthe critical buckling loadthe critical buckling load the critical buckling loadthe critical buckling loadthe critical buckling loadthe critical buckling load of plates. An accuracy of the present solutions is validated numerically by comparisons with some available results in the literature.
