“…Moreover, Ramezani et al [167] explored the NL FV responses of a cylindrical shells with a sandwich structure made of FG/SMA/FG analytically by implementing the HSDT with the semi assumed natural strain functions. Nonetheless, Sobhani et al [168] inspected the FV behavior of porous NCs cylindrical shells reinforced with Gr oxide powder to enhance the mechanical properties. The ROM and Haplin-Tsai (HT) were implemented to define the mechanical properties of the hybrid metal hybrid matrix and hybrid polymer matrix.…”

Recently, the mechanical performance of various mechanical, electrical, and civil structures, including static and dynamic analysis, has been widely studied. Due to the neuroma's advanced technology in various engineering fields and applications, developing small-size structures has become highly demanded for several structural geometries. One of the most important is the nano/micro-plate structure. However, the essential nature of highly lightweight material with extraordinary mechanical, electrical, physical, and material characterizations makes researchers more interested in developing composite/laminated-composite-plate structures. To comprehend the dynamical behavior, precisely the linear/nonlinear-free vibrational responses, and to represent the enhancement of several parameters such as nonlocal, geometry, boundary condition parameters, etc., on the free vibrational performance at nano/micro scale size, it is revealed that to employ all various parameters into various mathematical equations and to solve the defined governing equations by analytical, numerical, high order, and mixed solutions. Thus, the presented literature review is considered the first work focused on investigating the linear/nonlinear free vibrational behavior of plates on a small scale and the impact of various parameters on both dimensional/dimensionless natural/fundamental frequency and Eigen-value. The literature is classified based on solution type and with/without considering the size dependency effect. As a key finding, most research in the literature implemented analytical or numerical solutions. The drawback of classical plate theory can be overcome by utilizing and developing the elasticity theories. The nonlocality, weight fraction of porosity, or the reinforcements, and its distribution type of elastic foundation significantly influence the frequencies.

“…Song et al [34] employed the second-order shear deformation theory in curvilinear coordinate and analytical solution based on harmonic response to investigate wave dispersion responses of FG-GPL curved viscoelastic panels. Sobhani et al [35] employed FSDT and GDQ methods to evaluate the vibration behavior of graphene oxide powder composites joined paraboloidal-cylindrical shells with different boundary conditions. The effect of initial imperfection on the active control of FG-GPL cylindrical shells with piezoelectric layers due to the application of a proportional derivative smart controller was reported by Zare et al [36].…”

In this paper, the free vibration response of a stiffened functionally graded graphene nanoplatelet (GPL)-reinforced composite multilayer cylindrical shell panel is studied for the first time. The shell is stiffened by both stringers and rings. Additionally, the effect of reinforcing the shell panel, ring and stinger with GPLs is independently studied. Halpin–Tsai relations are employed to evaluate the mechanical properties of the shell panel, rings and stringers. The first-order shear deformation shell theory, accompanied by the Lekhnitsky smeared stiffener model, using the numerical finite element method and Hamilton principle, is employed to develop the governing motion equations of the shell panel. Four different types of GPL patterns, including FG-A, FG-X, FG-O and UD, are assumed across the thickness of the shell panel, rings and stringers. The effects of different factors, including various weight fractions and patterns of GPLs nanofillers, the geometry of the shell panel and stiffeners and two displacement boundary conditions, on the natural frequencies of the shell panel, have been studied.

“…Liu et al proposed an approximate analytical model for buckling analysis of common spherical-cylindrical-spherical composite structures by using the generalized Galerkin method [21]. Sobhani et al investigated the vibration of porous nanoenriched polymer composite coupled spheroidal-cylindrical shells, the wave frequency responses of the nanocomposite linked hemispherical-conical shell, the Circumferential vibration analysis of nano-porous sandwich assembled spherical-cylindrical-conical shells, and the Free vibration of porous graphene oxide powder nano-composite assembled paraboloid-cylindrical shells [22][23][24][25]. Rezaiee and Masoodi analyzed the buckling of plates and shell structures by an efficient triangular shell element which had six nodes with thirty degrees of freedom [26].…”

This study determined the buckling characteristics of sphere-segmented toroidal shells subjected to external pressure. The proposed toroidal vessel comprises six spheres and six rings. Two laboratory models with the same nominal dimensions were manufactured, measured, tested, and evaluated. To investigate whether sphere-segmented toroidal shells are imperfection-sensitive structures with closely spaced eigenvalues, the subspace algorithm was applied to evaluate the first 50 eigenmodes, and the modified Riks algorithm was used to obtain post-buckling characteristics. The results indicated that the deviation between the results of the experimental and numerical analyses was within a reasonable range. The proposed sphere-segmented toroidal shells were highly imperfection-sensitive structures with closely spaced eigenvalues. Subsequently, imperfection sensitivity analysis confirmed this conclusion. In numerical analyses, the first eigenmode could be considered as the worst eigenmode of sphere-segmented toroidal shells. The trend of the equilibrium path of sphere-segmented toroidal shells was consistent with spherical shells, revealing instability. In addition, ellipticity and completeness exerted a negligible effect on the buckling load of sphere-segmented toroidal shells.
