“…Due to the importance of using tapered thin-walled beams having open and close cross-sections in different engineering fields such as steel frames, decks of the bridge, mechanical, and especially aeronautical components, the static and dynamic analyses of thin-walled structural elements with various end conditions under different loading cases have been widely studied in recent decades. [1][2][3][4][5][6][7][8][9][10] Lateral torsional-buckling is one of the instability modes in which the slender and laterally unbraced tapered thin-walled open section beam subjected to bending about its strong axis may suddenly buckle in a flexural-torsional mode. The web and flanges tapering parameters, the load height position, internal bending moment, and boundary conditions are the main factors affecting the lateral-torsional buckling strength of thin-walled beams with varying cross-section.…”

In this research, the lateral buckling analysis and layup optimization of the laminated composite of web and flanges tapered thin-walled I-beams based on maximizing lateral-torsional stability strength and minimizing mass/cost of the structure are investigated. The classical lamination theory and Vlasov’s model for thin-walled cross-section are adopted to establish the total potential energy for thin-walled symmetric balanced laminated beams with varying I-section. By implementing the Ritz method, an explicit formulation for the lateral-torsional buckling load of a double-tapered beam subjected to transverse loading is then derived in terms of the load height parameter and stiffness quantities. Subsequently, the optimal arrangements of layer sequences are obtained using the non-dominated sorting genetic algorithm (NSGA-II) and properly defined objective function. The critical factors of fitness function as lateral buckling strength and the mass of the structure with critical limitations as ply angle, number of layers for the web and flanges, and the thickness of all section walls are considered in this study. Finally, the optimal layer arrangement for the web and flanges are separately determined and discussed. The results show that the presented optimization procedure and layups patterns lead to increasing the lateral-torsional buckling capacity about 52% compared to the conventional angle-ply and unidirectional layups for the web and flanges, respectively.

“…In recent years, many researchers have been studied the free vibration of laminated circular cylindrical shells considering various boundary conditions using Ralyleith–Ritz method (Lee and Kwak, 2015), hygroscopic environment (Zhao et al, 2015), sinusoidal shear deformation theory (Wang and Wu, 2017), beam modal function (Mohandes et al, 2017) and higher order sandwich panel theory (Malekzadehfard et al, 2017; Nekouei et al, 2019a). Ghasemi and Meskini (2019a, 2020) based on Love’s shell theory and Navier’s method have investigated the free vibration of rotating porous laminated circular cylindrical shells with various boundary conditions. Also, the effect of electro-magnetic potential on the natural frequency of functionally graded materials (FGM) cylindrical shell with piezo face sheet and laminated core illustrated.…”

Free vibration analysis of adhesive joins between two laminates circular cylindrical along with conical laminated composite shells considering various boundary conditions are examined. The numerical analysis are studied based on the first order shear deformation shell theory (FSDT) and considering compatibility conditions. Using Hamilton principle method, the governing equations of composite cylindrical shell lap adhesive joined to the composite conical shells are obtained. The analysis for carbon/epoxy, glass/epoxy and aramid/epoxy laminated composite materials and various type of adhesive materials are studied. For solving the equilibrium equations of lap joined the cylindrical to the conical shells with adhesive layer, the generalized differential quadrature method (GDQM) is used. The effect of circumferential wave number, length to radius ratio of the shell, length of overlap to length of shell ratio, thickness to radius ratio and thickness of adhesive to thickness of shell ratio are investigated. Furthermore, the various cone angles of conical shell, type of materials and adhesive layer on the natural frequency of laminated circular cylindrical connected to the conical shells are studied. In order to validate the numerical results of present analysis with previous research compared that the result shown that these comparisons show very good agreement. Numerical results shown that with increasing the value of cone angle of the conical shell and the ratio of overlap length to shell length, due to increasing the structural stiffness, the non-dimensional frequency of the structure with adhesive layer increased.

“…Zeng et al (2019) studied the size-dependent flexoelectric effect on the natural frequency and the nonlinear electromechanical behavior of cylindrical nanoshells based on the modified couple stress theory. By using the Hamilton’s principle and Navier’s solution, Ghasemi and Meskini (2019) investigated the free and linear vibration behavior of porous simply supported laminated rotating cylindrical shells.

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.
