In this paper, the influence of carbon nanotube (CNT) in a metal matrix on the buckling behavior of the resulting nanocomposite plate is studied. The Young's moduli of CNT reinforced nanocomposite are predicted first using the representative volume element (RVE) method. CNTs are considered to have the periodic spatial distribution in the RVE and their 3D orientations are randomized using COMSOL Multiphysics® Livelink™ for MATLAB® module. Thereafter, the effect of CNT reinforcement on the buckling behavior of simply-supported nanocomposite plate is predicted using the plate physics of COMSOL Multiphysics. The procedure to calculate the Young's modulus is verified by comparing the results of the single CNT reinforced RVE with the analytical solution obtained by the rule of mixtures.
