“…This foundation model is also called the two-parameter elastic foundation. The influences of two foundation parameters on the vibration and buckling of the cylindrical shell were discussed in the literature, [20][21][22][23][24] which can be used as a reliable source for the derivation of the basic equations, as a comparison of the results.…”

The main objective of this research work is focused on the vibration analysis of auxetic sandwich cylindrical shell structures resting on an elastic foundation. In the analysis, the sandwich shell structure is composed of three layers in which the middle layer consists of auxetic material with a negative Poisson’s ratio, and the two skin layers are isotropic homogeneous materials. The motion equation is extracted according to the first-order shear deformation theory (FSDT) and the Hamilton principle. The governing equations of coupled partial differential equations are solved by the generalized differential quadrature (GDQ) method, and the natural frequencies are determined. By comparing the experimental results with the numerical results calculated by commercial finite element software, the validity of the proposed theoretical model is verified. Finally, the influences of geometrical parameters and elastic foundation on the vibration behavior of sandwich shell structures have been investigated.

“…Alijani and Amabili (2014) presented the nonlinear vibration and multiple resonances of fluid-filled laminated circular cylindrical shells subjected to steady harmonic concentrated force by using the Amabili–Reddy nonlinear higher order shear deformation theory and energy approach in the Lagrangian description. The vibration characteristics of FGM cylindrical shells completely filled with fluid or subjected to a flowing fluid surrounded by Pasternak’s elastic foundation with nonparallel boundary edges were studied by Park and Kim (2016). Bidgoli et al (2016) and Arani et al (2016) investigated vibration and instability of functionally graded carbon nanotube–reinforced cylindrical shells conveying viscous fluid containing axially flowing and rotating fluid–particle mixture, respectively.…”

This article proposes a semianalytical approach for the nonlinear free and forced asymmetric vibration of corrugated sandwich functionally graded cylindrical shells containing fluid under harmonic radial load. The corrugation is considered with two types: trapezoidal corrugation and round corrugation. By using the Donnell shell theory, taking into account the geometrical nonlinearity of von Kármán and an equivalent model for corrugated structures, the governing equations of shell are established. The nonlinear motion equations are reduced to nonlinear differential equation in terms of time by applying the Galerkin procedure. The numerical investigations for the nonlinear dynamic response of cylindrical shells are obtained by using the fourth-order Runge–Kutta method. Numerical results show the very large effects of corrugation and fluid on the natural frequency and nonlinear vibration behavior of shells.

“…Monte Carlo simulation method was utilized by Alizade et al in conjunction with finite elements for probabilistic self‐excited vibration and stability analyses of pipes conveying fluid. The flow‐induced vibration characteristics (natural frequency and critical flow velocity) of functionally graded material cylindrical shells partially resting on elastic foundation were investigated by Park and Kim using an analytical method. Vibration and stability of concrete pipes reinforced with CNTs conveying fluid were presented by Zamani Nouri…”

In this article, vibration of nanoparticles reinforced‐concrete pipes surrounded by soil medium is presented. The nanoparticles are silica where the effective material properties of the structure are obtained by Mori–Tanaka model considering agglomeration of nanoparticles. The pipe is filled with a non‐viscous, compressible fluid. The surrounded soil medium is simulated by Winkler medium using spring element. The cylindrical shell model is used for modeling of the structure. Based on the energy method and Hamilton’s principle, the motion equations are derived. Using an exact solution, the frequency of the structure is calculated. The effects of fluid velocity, volume percent and agglomeration of silica nanoparticles, boundary condition, and geometrical parameters of pipe are shown on the instability response of the structure. Results show that considering the agglomeration of silica nanoparticles, the frequency of the concrete pipe is decreased.
