“…Free vibration analysis is a common practice for investigating the natural frequency of structures in many industrial applications. In this regard, Jooybar et al , Ghorbani Shenas et al , and Malekzadeh et al studied free vibration of functionally graded carbon nanotube reinforced composite (FG‐CNTRC) plates/beams/conical panels, under a moving load, and in thermal environment. Furthermore, for FG‐CNTRC skew plates, low velocity impact was studied using the finite element method (FEM) in combination with Newmark's time integration method by Malekzadeh and Dehbozorgi .…”

Free vibration analysis of size‐dependent carbon nanotube‐reinforced composite (CNTRC) nanoplates, resting on the visco‐Pasternak foundation is studied. The Mori–Tanaka approach, considering carbon nanotube (CNT) agglomeration, is employed to derive the material properties of the composite nanoplates. The analysis is carried out for the uniform distribution (UD) and randomly oriented (RO) distribution of single‐walled carbon nanotubes (SWCNTs) while the nanoplate and the foundation are considered to be temperature‐dependent. Using Hamilton's principle, the governing differential equations are derived based on the Eringen's nonlocal elasticity theory and sinusoidal shear deformation theory (SSDT). The natural frequency of the nanoplates is then obtained by the Navier's analytical solution. To verify the method presented, the results are compared with those in the literature. Detailed parametric studies are performed to discuss the influences of CNTs agglomeration, nonlocal parameter, temperature, foundation parameters, the volume fraction of CNTs, plate length‐to‐thickness, and aspect ratios on the free vibration of the CNTRC nanoplates.

“…Moreover, these initial studies only applied traditional finite element methods for analyzing structures. Recently, some extensional studies in these trends of research have been carried out such as applying new numerical methods like Isogeometric Analysis (IGA) method, 26 Lagrangian multipliers, 27 meshless method, 28 multiple time-scale method, 29 semi-analytical method 30 or more complex structures 31,32 or considering various loads like the impact load, 33 moving load, 34,35 thermal load, 36 parabolic loading 37 or investigating influence of thermal 38–40 or integrating with piezoelectric 41,42 and so on.…”

The paper presents an efficient numerical optimization approach to deal with the optimization problem for maximizing the fundamental frequency of laminated functionally graded carbon nanotube-reinforced composite quadrilateral plates. The proposed approach is a combination of the cell-based smoothed discrete shear gap method (CS-DSG3) for analyzing the first natural frequency of the functionally graded carbon nanotube reinforced composite plates and a global optimization algorithm, namely adaptive elitist differential evolution algorithm (aeDE), for solving the optimization problem. The design variables are the carbon nanotube orientation in the layers and constrained in the range of integer numbers belonging to [−900 900]. Several numerical examples are presented to investigate optimum design of quadrilateral laminated functionally graded carbon nanotube reinforced composite plates with various parameters such as carbon nanotube distribution, carbon nanotube volume fraction, boundary condition and number of layers.
