“…[116][117][118][119] Using the Halpin-Tsai micromechanics model and combination law, Polit et al 119 studied the constant bending of GPLs that strengthened the porous curved NCs beam and found that the pattern of weight distribution, size ratio, and increase in the curve of the GPL curve significantly affected the stiffness and lowering of the pole. Tam et al 120 examined the non-linear bending structures of integrated graphene nano-platelet-reinforced beams that are reinforced on both sides and open seam openings using modelling auxiliary materials that deal with non-aligned material FG-GPL on the edge of crack defect and support stretching.…”

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.

Graphene is a highly conductive and exceptional material that has shown potential for significantly improving the piezoelectric and mechanical properties of piezoelectric matrix. This paper examines the stability of composite plates surface bonded with graphene‐reinforced composite piezoelectric (GRCP) actuators. However, the significant differences in material characteristics at the interfaces will pose some challenges in analyzing the buckling behavior of piezoelectric composite plates by means of existing higher‐order shear deformation theories. To address this issue, a refined plate theory is developed for the buckling analysis of piezoelectric composite plates. The developed theory includes a new interlaminar shear stress field that precisely describes the distribution of interlaminar shear stresses, which differs from earlier higher‐order theories. It should be emphasized that the finite element formulation can be simplified by removing the second‐order derivatives of in‐plane displacement parameters from interlaminar shear stresses. In terms of the developed theory, a four‐node C0 quadrilateral plate element is introduced to examine the buckling behavior of piezoelectric composite plates. Furthermore, the modified interlaminar shear stress field is absorbed into the strain energy, significantly improving the ability to predict the critical loads of composite plates with GRCP actuators. The refined plate model is evaluated through the utilization of three‐dimensional (3D) elasticity solutions and results obtained from other associated theories. Numerical results demonstrate that the refined plate model is capable of producing favorable results, and a comprehensive examination is conducted to analyze the effects of significant parameters on the buckling behaviors of piezoelectric composite plates. This study sets a solid foundation for future research and development on the application of graphene‐reinforced composite piezoelectric actuators in composite structures.Highlights Buckling analysis of composite plates with GRCP actuators is conducted. A refined plate theory with modified interlaminar shear stresses is developed. The ability to predict critical loads can be significantly improved. The finite element formulation can be simplified based on the proposed model. Comprehensive parametric studies on buckling behavior are caried out.

“…The carbon nanotube (CNT) is a remarkable reinforcement for composite materials with excellent mechanical, electrical, absorbance, and thermal conduction properties (Chen et al, 2018;Li et al, 2020;Wang et al, 2021a;Wang et al, 2022), including light weight, superior stiffness, and strength, and is commonly used in aerospace, automotive, and civil engineering fields (Zhang et al, 2022). The functionally graded materials (FGMs) are inhomogenous composites, and the material properties change smoothly and continuously along one or more directions (Li et al, 2019;Tam et al, 2020;Yang et al, 2021a). Compared with laminated materials, FGMs are able to reduce thermal stresses, residual stresses, and stress concentration factors (Datta, 2021).…”

Piezoelectric materials possess excellent electromechanical coupling characteristics, which are functional and suitable in structural vibration control. This study investigates the active control of free and forced vibration for piezoelectric-integrated functionally graded carbon nanotube reinforced composite (FG-CNTRC) plate using the finite element method (FEM). Based on the first-order shear deformation theory (FSDT), the governing equations of the motion of a piezoelectric-integrated FG-CNTRC plate are derived by Hamilton’s principle. The convergence and accuracy of the numerical method is verified through the results of natural frequencies. The influences of CNT volume fraction, CNT distribution type, piezoelectric layer thickness-to-plate thickness ratio, and boundary condition on the natural frequencies are investigated. A constant gain velocity feedback algorithm is used to achieve the dynamic response control of the piezoelectric-integrated FG-CNTRC plate. In addition, the effects of dynamic load, feedback control gain, and boundary condition on the dynamic response of the plate are studied. Numerical results indicate that active control is promising for practical applications in civil and mechanical engineering.
