“…The multi-layer beam FE has been presented for buckling of laminated composite beam with improved element accuracy by considering the higher-order polynomials. 136 Further, Tam et al 137,138 have investigated the buckling behaviour of Gr-NCs with open edge cracks using first-order shear deformation theory (FSDT) and finite element method (FEM)-based analytical approaches. They concluded that the critical buckling load of the FG graphene platelet NCs structure was affected by the crack in the structure.…”

Graphene is playing an important role in the enhancement of new composite materials and is capable of enhancing the performance and functionality of many applications. Graphene-reinforced structures are used in nano-sized systems, energy storage devices, automotive and combustible devices, defence system, aerospace systems, medical instruments, biomedical system, and electronics devices. Due to the crucial mechanical behaviour of nano-structures design, the complete understanding of the flexural, buckling, and vibration analysis of various nanocomposite (NC) structures such as beams, plates, and shells have received great attention in recent years. The present article reviews the synthesis techniques of graphene-reinforced nanocomposites (Gr-NCs). The article also discusses the existing micromechanics models to determine the mechanical properties of Gr-NCs. The comprehensive review also presents a detailed assessment on mechanical analysis and applications of Gr-NCs structures. The article further discusses the future scope and technical challenges that may help in the appropriate design and analysis of graphene nanosystems, applicable in the various field of nanotechnology and nanocomposite materials. The purpose of the present review is to critically review the existing development in Gr-NCs and provide the comprehensive overview of Gr-NCs. By reinforcing graphene and its derivatives into the matrix, the resulting composite may enhance the functionality and explore new NCs for of various nanostructures.

“…In general, aeronautical companies use FEM in structural analyses, vibrations, dynamic buckling and fluid flows in the fuselage, wing, turbine and other parts ( Figure 39) [284][285][286]. These analyses help determine the best geometry and material for each part of the aircraft, and understand how it will behave in service; for example, how the pressure and drag force will affect the aircraft during a flight [285,287].…”

The use of composite materials in several sectors, such as aeronautics and automotive, has been gaining distinction in recent years. However, due to their high costs, as well as unique characteristics, consequences of their heterogeneity, they present challenging gaps to be studied. As a result, the finite element method has been used as a way to analyze composite materials subjected to the most distinctive situations. Therefore, this work aims to approach the modeling of composite materials, focusing on material properties, failure criteria, types of elements and main application sectors. From the modeling point of view, different levels of modeling—micro, meso and macro, are presented. Regarding properties, different mechanical characteristics, theories and constitutive relationships involved to model these materials are presented. The text also discusses the types of elements most commonly used to simulate composites, which are solids, peel, plate and cohesive, as well as the various failure criteria developed and used for the simulation of these materials. In addition, the present article lists the main industrial sectors in which composite material simulation is used, and their gains from it, including aeronautics, aerospace, automotive, naval, energy, civil, sports, manufacturing and even electronics.

“…By introducing GPLs to FGM materials, novel FG GPLs-reinforced composite (FG-GPLRC) structures have been developed recently and have since attracted extensive attention in both research and engineering communities [24]. Yang and his co-workers conducted pioneering studies on the mechanical behaviors of FG-GPLRC structures, such as beams [25][26][27][28], shells [29,30], and plates [31,32]. Focusing on the stability analysis of FG-GPLRC arches, the authors devoted extensive efforts to the investigation of such structures, including the characteristics of nonlinear static buckling, dynamic buckling, and free vibration for FG-GPLRC arches with different boundary conditions and external loads [33][34][35][36][37][38][39].…”

In this paper, we present an analytical prediction for nonlinear buckling of elastically supported functionally graded graphene platelet reinforced composite (FG-GPLRC) arches with asymmetrically distributed graphene platelets (GPLs). The effective material properties of the FG-GPLRC arch are formulated by the modified Halpin–Tsai micromechanical model. By using the principle of virtual work, analytical solutions are derived for the limit point buckling and bifurcation buckling of the FG-GPLRC arch subjected to a central point load (CPL). Subsequently, the buckling mode switching phenomenon of the FG-GPLRC arch is presented and discussed. We found that the buckling modes of the FG-GPLRC arch are governed by the GPL distribution pattern, rotational restraint stiffness, and arch geometry. In addition, the number of limit points in the nonlinear equilibrium path of the FG-GPLRC arch under a CPL can be determined according to the bounds of successive inflexion points. The effects of GPL distribution patterns, weight fractions, and geometric configurations on the nonlinear buckling behavior of elastically supported FG-GPLRC arches are also comprehensively discussed.
