“…Wang et al 111 have studied the non-linear bending of the graphene-reinforced NCs pole by looking at diesel approval. Polit et al 112 have highlighted the effect of symmetric distribution, size-to-thickness and angle of the curved log on static and dynamic structures of functionally graded (FG) porous materials which depend on the concept of trigonometric shear deformation theory. The flexural stiffness is found greater for symmetry distribution GPLs.…”

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.

“…However, more controlled and specified properties like structural stiffness, electrical conductivity, and energy absorption can be achieved by varying the size and density of internal pores in a functionally graded manner. [1][2][3][4][5][6][7][8][9][10] Such artificially engineered materials are called functionally graded porous materials (FGPMs) which of course possess light-weight, but they lose their stiffness/strength significantly. 11,12 The compensation for the reduction of stiffness/strength may be accomplished with reinforcement of carbonaceous nanofiller such as graphene nanoplatelets (GPLs) because of its high elastic modulus around 1 TPa.…”

The present study explores the stochastic natural frequency of graphene reinforced functionally graded porous panels with unconventional boundary conditions. The material uncertainty is considered in the parameters associated with constituents that is, metal and graphene nanoplatelets (GPLs) individually and simultaneously. The metal matrix is reinforced with ultra-lightweight and high stiffness carbonaceous nanofiller, that is, GPLs. Halpin-Tsai micromechanics model is adopted to estimate effective Young’s modulus of the metal-GPLs composite whereas effective mass density and Poisson’s ratio are calculated using the Voigt model. The micro-structural gradation by creating pores is accomplished along the thickness direction of the panel employing certain continuous functions. These functions describe symmetric and asymmetric porosity distributions and associated patterns of GPLs. The equation of motion is developed using Euler-Lagrange’s equation which is based on C0-continuous structural kinematics with 7 degrees of freedom. Finite element modeling in conjunction with the first-order perturbation technique has been applied to quantify the stochastic natural frequency in terms of the mean and standard deviation of the natural frequency. Various results have been examined to highlight the influence of parameters especially related to porosity, and graphene nanoplatelets on the stochastic natural frequency of FG-GPLs porous panel constrained with conventional and unconventional boundary conditions.

This paper conducted the free vibration analysis of a sandwich annular thin plate with whirl motion. The upper and lower faces of the annular plate are made of uniform solid metal, while its core is porous foamed metal reinforced by graphene nanoplatelets (GPLs). Both uniform and non-uniform distributions of GPLs and porosity along the direction of plate thickness which leads to a functionally graded (FG) core are taken into account. The effective material properties including Young’s modulus, Poisson’s ratio and mass density are calculated by employing the Halpin–Tsai model and the rule of mixture, respectively. Based on the Kirchhoff plate theory, the differential equations of motion are derived by applying the Lagrange’s equation. Then, the assumed mode method is utilized to obtain free vibration behaviors of the sandwich annular plate. The finite element method is adopted to verify the present model and vibration analysis. The effects of porosity coefficient, porosity distribution, graphene nanoplatelet (GPL) distribution, graphene nanoplatelet (GPL) weight fraction, graphene nanoplatelet length-to-thickness ratio (GPL-LTR), graphene nanoplatelet length-to-width ratio (GPL-LWR), spinning speed, outer radius-to-thickness ratio and inner radius-to-thickness ratio of the plate, are examined in detail.
