“…In order to examine the stability responses of MSH nanocomposite structures based on smart shape memory alloy (SMA) with account of the effect of heat gradient as well as moisture concentration, Karimiasl, Ebrahimi, and Akgöz [171] adapted the TSDT for the doubly-curved shells. Additionally, a vibration study project to ascertain the free and forced vibrational properties of MSH smart nanocomposite doublycurved shells took the nonlinearity effects into account [172,173].…”

The research conducted by many scientists and engineers on nanocomposite materials and continuous systems made from such materials will be reviewed historically in this article by the writers. Nano composites are a form of well-known composite material that has been improved by adding nanoscale fibers and/or particles for reinforcement. These materials may be more appropriate for industrial applications that require material qualities that are noticeably improved. In other words, because of the improved properties of materials at the nanoscale, the material properties of nanocomposites are superior to those of macroscale composites. Designers are using these materials more frequently than traditional composite materials as constituent parts in aerospace, mechanical, and automotive applications. In order to forecast how buildings made of these materials will behave under actual operating conditions, it is crucial to be aware of the research that has been done in this field. The mechanical analyses carried out on various nanocomposite structures, such as those reinforced with carbon nanotubes (CNTR), graphene (GR), graphene platelets (GPLR), graphene oxide (GOR), and multi-scale hybrid (MSH) nano-composite ones, will be reviewed in the sections that follow, along with the most significant aspects of the suggested scientific activities.

The aim of the present research is to investigate the nonlinear dynamic and forced vibration of a composite sandwich panel embedded with piezoelectric layers under thermo-harmonic loading. The panel consists of a double-U auxetic honeycomb core made of aluminum alloy and graphene platelet reinforced composite (GPLRC) skins at the top and bottom surfaces. According to Gibson’s formula, the effective material properties of facing sheets and double-V auxetic core are considered. The nonlinear equations are obtained by applying Hamilton’s principles via von Karman’s nonlinear theory and higher-order shear deformation theory (HSDT). The governing equations of motion are solved by employing the differential quadrature method (DQM) and homotopy perturbation method, respectively. The accuracy of the current results has been verified by comparison with others in the literature. Finally, the influence of different parameters such as applied voltage, magnetic potential, temperature rise, different boundary conditions, and geometric parameters of core on the nonlinear frequency-amplitude response of cylindrical panels are analyzed. The numerical results show negative effect of temperature increment, positive influence of ratio of thickness to inclined length, core thickness, amplitudes of segments, considerable effect of the magnetic potential as well as small effect of applied voltage on the nonlinear vibration of sandwich panel. Finally, the important findings of this research indicate that the magnetic potential, amplitude segment, and length to inclined cell rib length have significant effects on nonlinear dynamic deflection and frequencies-amplitude response. Based on the results of this article, designers can develop different parts of aircraft.
