“…Contrary to the piezoelectricity, flexoelectricity exits only in all dielectric materials. In addition to this, for the active control of lightweight smart structures subjected to static/dynamic loading conditions, these piezoelectric structures with flexoelectric effect plays significant role [6][7][8][9][10]. For instance, the most common and extensively used monolithic piezoelectric materials are lead zirconate titanate (PZT) and polyvinylidene fluoride (PVDF).…”

“…They have also carried out static and dynamic characteristic including sensitivity and frequency analysis of laminated composite and FG material by using probabilistic and non-probabilistic uncertainty quantification approach. Recently, Kundalwal and co-authors [10,[33][34][35] studied the electromechanical response of graphene-based nanocomposite (GNC) and its different structural elements, such as beam, plate, wire and shell, by incorporating piezoelectric graphene nanofiber in polyimide matrix. They predicted the overall effective properties of GNC, using analytical and numerical models.…”

Owing to their applications in devices such as in electromechanical sensors, actuators and nanogenerators, the consideration of size-dependent properties in the electromechanical response of composites is of great importance. In this study, a closed-form solution based on the linear piezoelectricity, Kirchhoff’s plate theory and Navier’s solution was developed, to envisage the electromechanical behaviors of hybrid graphene-reinforced piezoelectric composite (GRPC) plates, considering the flexoelectric effect. The governing equations and respective boundary conditions were obtained, using Hamilton’s variational principle for achieving static deflection and resonant frequency. Moreover, the different parameters considering aspect ratio, thickness of plate, different loadings (inline, point, uniformly distributed load (UDL), uniformly varying load (UVL)), the combination of different volume fraction of graphene and piezoelectric lead zirconate titanate are considered to attain the desired bending deflection and frequency response of GRPC. Different mode shapes and flexoelectric coefficients are also considered and the results reveal that the proper addition of graphene percentage and flexoelectric effect on the static and dynamic responses of GRPC plate is substantial. The obtained results expose that the flexoelectric effect on the piezoelastic response of the bending of nanocomposite plates are worth paying attention to, in order to develop a nanoelectromechanical system (NEMS). Our fundamental study sheds the possibility of evolving lightweight and high-performance NEMS applications over the existing piezoelectric materials.

“…Similar boundary and loading conditions can be applied for obtaining the remaining elastic coefficients such as C 11 , C 12 , C 13 , C 23 , C 33 , C 44 , and C 66 . The detailed steps required for the determination of these coefficients are described elsewhere (Kundalwal et al, 2019(Kundalwal et al, , 2020a(Kundalwal et al, , 2020bShingare and Kundalwal, 2019a;Shingare and Kundalwal, 2020). As we know, every FE analysis is divided into pre-processing, computation and post-processing steps.…”

“…They showed the enhancement in the active damping property of the smart structures, which caused a reduction in respective vibrations. Most recently, a graphene-based PZC was also being studied by Shingare et al [23][24][25][26] They predicted electromechanical properties of the graphene-based nanocomposites with micromechanical model based on the mechanics of materials (MOM), 27 modified strength of materials and finite element (FE) approach. Their results showed enhanced out-ofplane piezoelectric constant (e 33 ) as compared to inplane piezoelectric constant (e 31 ); the similar trend was also observed by Ray and Batra team.…”

In this work, the carbon nanotube-based hybrid carbon fibre-reinforced composite smart beam constraining the layer of an active constrained layer damping treatment is investigated using an in-house finite element model based on first-order shear deformation theory. The effect of in-plane and transverse-plane actuation of the integrated active constrained layer damping treatment layer on the damping characteristics of the novel smart cantilever hybrid carbon fibre-reinforced composite beam is considered. The parameters affecting the damping characteristics of the hybrid carbon fibre-reinforced composite substrate beam such as the volume fraction of both carbon nanotubes and carbon fibre, and the aspect ratio are also studied. Besides, the micromechanical model based on the mechanics of materials approach is developed to estimate the effective elastic coefficient of novel hybrid carbon fibre-reinforced composite lamina. The effective properties of hybrid carbon fibre-reinforced composite are predicted quantitatively by considering non-bonded interaction formed between carbon nanotubes and the polymer matrix. It is revealed that due to the incorporation of carbon nanotubes into the epoxy matrix, the effective longitudinal, transverse and shear properties of the hybrid carbon fibre-reinforced composite lamina are significantly enhanced. Our outcomes explore that the damping performance of the laminated hybrid carbon fibre-reinforced composite smart beam considering the incorporation of carbon nanotubes shows substantial improvement as compared to the base composite. To bring more clarity, the quantitative relative performance of hybrid carbon fibre-reinforced composite and base composite is presented. Our fundamental analysis sheds the light on the opportunities of developing efficient, high-performance and lightweight carbon nanotubes-based micro-electro-mechanical systems smart structures such as sensors, actuators and distributors.
