“…Linear and nonlinear stability of FG-CNTRC cylindrical panels have been addressed in works [18][19][20][21][22][23]. Nasihatgozar et al [18] employed the analytical solution to study linear buckling of FG-CNTRC cylindrical panels with piezoelectric layer under axial compression. Basing on a numerical approach with shell finite element, Macias et al [19] analyzed linear buckling of FG-CNTRC cylindrical panels under axial compression and shear.…”

Buckling and postbuckling behaviors of Toroidal Shell Segment (TSS) reinforced by single-walled carbon nanotubes (SWCNT), surrounded by an elastic medium and subjected to uniform external pressure are investigated in this paper. Carbon nanotubes (CNTs) are reinforced into matrix phase by uniform distribution (UD) or functionally graded (FG) distribution along the thickness direction. Effective properties of carbon nanotube reinforced composite (CNTRC) are estimated by an extended rule of mixture through a micromechanical model. Governing equations for TSSs are based on the classical thin shell theory taking into account geometrical nonlinearity and surrounding elastic medium. Three-term solution of deflection and stress function are assumed to satisfy simply supported boundary condition, and Galerkin method is applied to obtain nonlinear load-deflection relation from which buckling loads and postbuckling equilibrium paths are determined. The effects of CNT volume fraction, distribution types, geometrical ratios and elastic foundation on the buckling and postbuckling behaviors of CNTRC TSSs are analyzed and discussed.

“…The change of CNT volume fraction, temperature, as well as state of loading had a significant influence on the plate buckling strengths. Similarly, the buckling study of cylindrical CNT‐reinforced composite panels was performed using the Mori–Tanaka method by Nasihatgozar et al . The effects of various parameters such as CNT volume fraction, loading types (axial and biaxial), and geometrical ratios of the composite panel on the buckling response of panels were studied.…”

Free vibration analysis of size‐dependent carbon nanotube‐reinforced composite (CNTRC) nanoplates, resting on the visco‐Pasternak foundation is studied. The Mori–Tanaka approach, considering carbon nanotube (CNT) agglomeration, is employed to derive the material properties of the composite nanoplates. The analysis is carried out for the uniform distribution (UD) and randomly oriented (RO) distribution of single‐walled carbon nanotubes (SWCNTs) while the nanoplate and the foundation are considered to be temperature‐dependent. Using Hamilton's principle, the governing differential equations are derived based on the Eringen's nonlocal elasticity theory and sinusoidal shear deformation theory (SSDT). The natural frequency of the nanoplates is then obtained by the Navier's analytical solution. To verify the method presented, the results are compared with those in the literature. Detailed parametric studies are performed to discuss the influences of CNTs agglomeration, nonlocal parameter, temperature, foundation parameters, the volume fraction of CNTs, plate length‐to‐thickness, and aspect ratios on the free vibration of the CNTRC nanoplates.

Today, due to the undeniable importance of smart materials such as shape memory alloys (SMAs), their application in engineering structures has become widespread. So, investigating their various properties is the subject of many studies.According to Reddy's higher-order shear deformation theory and von K arm an nonlinearity, this research presented the buckling characteristics of SMA composite sandwich panel with a viscoelastic core. The governing equations of the panel are derived by implementing Hamilton's principle. For investigating the accuracy, this article is validated with other previous researches, and a good correlation is observed between the results. Finally, different parameters such as volume fraction of SMA, the thickness of the viscoelastic core, geometry ratios, and magnetic fields are considered in this article. The results show that the critical buckling response decreased by increasing the magnitude of magnetic potential. But it has a small influence on the real part of the critical buckling load of sandwich composite panel.
