1. Introduction
Due to their exceptional mechanical properties, carbon nanotubes (CNTs) are known as an excellent candidate to reinforce the composites. CNTs have higher elasticity modulus in comparison to the polymeric and metallic matrices which results in a composite with enhanced stiffnesses. Therefore, volume fraction of CNTs is an important factor on structural response of composites reinforces with CNTs. Another factor which may affect the global and local structural response of a composite media reinforced with CNTs is their distribution pattern. Distribution of CNTs in a matrix may be uniform or functionally graded according to a prescribed function. An overview of the available works on the mechanical and thermal properties of a composite media is provided by Liew et al. [1]. As shown by Shen [2], mechanical response of a rectangular plate may be enhanced with the introduction of a prescribed functionally graded pattern for the CNTs. Shen [2] exhibited that, bending moments of the plate may be alleviated significantly with the introduction of functionally graded CNTs where the top and bottom surfaces of the plate are enriched with the maximum volume fraction of CNT and the midsurface is free of CNT. Following this research, various investigators analysed the structural behaviour of CNT reinforced composites in various shapes. An overview of the available works on the vibration of plates made of functionally graded carbon nanotube reinforced composites (FG-CNTRC) is provided in the next paragraphs. Based on the first order shear deformation plate theory and finite elements formulation, natural frequencies of an FG-CNTRC plate are obtained by Zhu et al. [3]. Free vibration of rectangular plates [4] and skew plates [5] are investigated by Zhang et al. using the element free methods. In two other studies, also, Zhang et al. [6,7] examined the free vibration characteristics of elastically restrained rectangular plates and plates which are simply supported in two opposite edges. For rectangular plates which are resting on elastic foundation, Zhang et al. [8] investigated the free vibration characteristics using an element free moving least squares Ritz formulation. For rectangular laminated plates with general boundary conditions and composed of FG-CNTRC layers, Lei et al. [9] investigated the free vibration characteristics using an element free method. Free vibration behaviour of FG-CNTRC plates in an arbitrary quadrilateral shape is investigated by Malekzadeh and Zarei [10] based on a two-dimensional generalised differential quadrature method. Malekzadeh and Heydarpour [11] developed a mixed solution method based on Navier and Layerwise formulations to investigate the free vibration characteristics of sandwich rectangular plates containing the FG-CNTRC layers. Due to the adoption of Navier solution method, plates which are simply supported all around may be analysed only. A higher order shear deformation
