In particular, consideration of the buckling phenomena in such plates is essential for the efficient and reliable design and for the safe use of the structural element. Due to the anisotropic and coupled material behavior, the analysis of composite laminated plates is generally more complicated than the analysis of homogeneous isotropic ones.

Buckling Analysis of Composite Laminated Plate with Cutouts. Introduction. Composite laminated plates when loaded in compression are subjected to a type of behavior known as buckling as long as the load on the plate is relatively small, then any increase in the load results only in an axial shortening of the plate.
In this study, a buckling analysis was performed on square plates made of composite material with and without elliptical notch using the finite element method. The boron/epoxy laminated plates were asymmetrically orderly arranged into the following way / .

There are many investigations about buckling analysis of composite plates, but in the existing literature no work has been done on the buckling analysis of laminated composite circular plates having circular holes.
The results presented in this article indicate that the thermal post-buckling behaviors of carbon nanotube- reinforced composite CNTRC plates are significantly influ- enced by the thermal load ratio, the transverse shear deforma- tion, the plate aspect ratio as well as the nanotube volume fraction.

laminated plates are of carbon fiber reinforced composite materials. Laminated composite plate with circular cutout shows a decrease in buckling load than plates without cutout. Key Words: Buckling Analysis, Finite Element Method, Circular Cutouts, Carbon Fibre, Laminated Composite Plate 1. INTRODUCTION
Buckling analysis of laminated composite plates is carried out by using an efficient C0 FE model developed based on higher order zigzag theory. In this model the first derivatives of transverse displacement have been treated as independent variables to overcome the problem of C1 continuity associated with the FE implementation of the plate theory.
