“…[28][29][30] Several studies have been conducted to explore the mechanical properties of graphene-based composites. [31][32][33] Kitipornchai et al [34] used a continuum model to analyze vibration with different mode shapes of multilayered graphene sheets. They showed that by varying the number of layers in a multilayered graphene sheet, different resonance modes can be determined.…”

This article explores the coupled static and dynamic electromechanical responses of single and multilayered functionally graded (FG) graphene platelet (GPL)-reinforced piezoelectric composite (GRPC) plates by developing a 3D finite-element model. The bending and eigenfrequency of piezoelectric FG composite plates are investigated, wherein an active behavior is proposed to be exploited in terms of the functional design of poling angle for a more elementary level property modulation. The numerical results reveal that the mechanical behavior concerning deflection and resonance frequency of FG-GRPC plates can be significantly enhanced and modulated due to the influence of piezoelectricity and a small fraction of GPLs along with the consideration of poling angle in a multiscale fully integrated computational framework. The notions of on-demand property modulation, actuation, and active control are established here by undertaking a comprehensive numerical analysis considering the coupled influences of poling orientations, different distributions, patterns, and weight fractions of GPLs along with different electromechanical loadings. Against the backdrop of the recent advances in microscale manufacturing, the current computational work will provide necessary physical insights in modeling piezoelectric multifunctional FG composites for active control of mechanical properties and harvesting electromechanical energy in a range of devices and systems.

“…Its one atomic thick two dimensional (2D) nature gives rise to some exceptional phenomena such as ultra-high electron mobility [6,7], superior thermal conductivity [8], unconventional quantum Hall effect [9], generation of massless Dirac fermions [10,11] etc along with extraordinary mechanical properties in terms of strength and Young's modulus [12][13][14]. Graphene and its different derivatives along with the effect of defects and doping have been at the centre of attraction over the last decade for exploring various multifunctional properties [15][16][17][18][19][20][21][22][23][24]. The physical properties vary significantly when two or more layers come into play (referred to as nano-heterostructure [25][26][27]) due to interlayer coupling, stacking sequences, and twisting.…”

Two-dimensional materials with a single or few layers are exciting nano-scale materials that exhibit unprecedented multi-functional properties including optical, electronic, thermal, chemical and mechanical characteristics. A single layer of different 2D materials or a few layers of the same material may not always have the desired application-specific properties to an optimal level. In this context, a new trend has started gaining prominence lately to develop engineered nano-heterostructures by algorithmically stacking multiple layers of single or different 2D materials, wherein each layer could further have individual twisting angles. The enormous possibilities of forming heterostructures through combining a large number of 2D materials with different numbers, stacking sequences and twisting angles have expanded the scope of nano-scale design well beyond considering only a 2D material mono-layer with a specific set of given properties. Magic angle twisted bilayer graphene, a functional variant of van der Waals heterostructures, has created a buzz recently since it achieves unconventional superconductivity and mott insulation at around 1.1o twist angle. These findings have ignited the interest of researchers to explore a whole new family of 2D heterostructures by introducing twists between layers to tune and enhance various multi-physical properties individually as well as their weighted compound goals. Here we aim to abridge outcomes of the relevant literature concerning twist-dependent physical properties of bilayer graphene and other multi-layered heterostructures, and subsequently highlight their broad-spectrum potential in critical engineering applications. The evolving trends and challenges have been critically analysed along with insightful perspectives on the potential direction of future research.

“…These studies reveal that an increase in the nonlocal parameter can reduce the loss factor in a significant way due to the coupling between the nonlocalities in the spatial and temporal domains. Most recently, Naskar et al 42 introduced a very powerful semianalytical ''Extended Kantorovich method'' in conjunction with MCST to analyze the static and dynamic response of flexoelectric FG plate at the nanoscale in the presence of surface and piezoelectric effect.…”

Nanoscale beams and rods are extensively used in several nano-electro-mechanical systems (NEMS) and their applications such as sensors and actuators. The surface and flexoelectricity phenomena have an extensive effect on nanosized structures and are related to their scale-dependent characteristics. This article presents the effect of different surface parameters and flexoelectricity on the electrostatic response of graphene-reinforced hybrid composite (GRHC) nanorods (NRs) using the theory of linear piezoelectricity, Euler-Bernoulli (EB), and Galerkin residual method. Based on these theories, the theoretical and finite element (FE) model is produced to investigate the static bending deflection of GRHC NRs when subjected to point and uniformly distributed load (UDL) considering different boundary conditions: cantilever (FC), fixed-fixed (FF), and simply supported (SS). This proposed FE model provides a useful tool for analyzing and investigating the outcomes of analytical models, which are found to be in good agreement. Our results presented in this article reveal that the effect of surface and flexoelectricity on the static bending response of GRHC NRs is noteworthy. These effects diminish with increased thickness/diameter of NR, and hence, these effects can be neglected for large-sized structures. The results presented here would help to identify the desired electrostatic response of GRHC NRs in terms of static bending response for a range of NEMS using different loading and boundary conditions as well as graphene volume fraction. This current study offers pathways for developing new proficient novel GRHC materials with enhanced control authority and present models can be exploited for numerous other materials as well as line-type structural systems such as beams, wires, rods, column/piers, and piles to study their global response.
