In this paper, the buckling analysis of laminated composite plates reinforced by single-walled carbon nanotubes (SWCNTs) is carried out using an analytical approach as well as the finite element method. The developed model is based on the classical laminated plate theory (CLPT) and the third-order shear deformation theory for moderately thick laminated plates. The critical buckling loads for the symmetrical layup are determined for different support edges. The Mori-Tanaka method is employed to calculate the effective elastic modulus of composites having aligned oriented straight nanotubes. The effect of the agglomeration of the randomly oriented straight nanotubes on the critical buckling load is also analyzed. The results of analytical solution are compared and verified with the FEM calculations The critical buckling loads obtained by the finite element and the analytical methods for different layup and boundary conditions are in good agreement with each other. In this article, the effects of the carbon nanotubes (CNTs) orientation angle, the edge conditions, and the aspect ratio on the critical buckling load are also demonstrated using both the analytical and finite element methods.

“…As observed from recent literatures, 12 the overall percentage error in results of various structural analysis problems is less with the new Inverse Hyperbolic Shear Deformation Theory (IHSDT), which is a Non-Polynomial Shear Deformation Theory (NPSDT), compared to other existing shear deformation theories. Many researchers analysed buckling of plates due to inplane mechanical loads [13][14][15][16][17][18][19] and due to the thermal loads [20][21][22][23][24][25][26][27] using finite element method. The presence of damage affects the reliable operation of the structure.…”

This paper deals with the incorporation of Inverse Hyperbolic Shear Deformation Theory (IHSDT), optimization with Unified Particle Swarm Optimization (UPSO) method and damage incorporation in buckling analysis of composite structures which all has received no attention yet. In the present investigation, buckling and post buckling analysis under hygrothermal loads using IHSDT, optimization of the critical buckling temperature of laminated plates considering the fiber orientation as design variable by employing a UPSO algorithm, effect of damage in buckling behaviour using an anisotropic damage model, etc. of laminated composite plates are discussed. FEM formulation and programming in MATLAB environment have been done. Optimized critical buckling temperature of laminated plates with internal flaw is found out with the fiber orientation as design variable. The outcomes and remarks from this work will assist to address some key issues concerning composite structures.
