“…This is confirmed by a large number of papers and books. The finite elements method (FEM) is one of the most widely applied approach to non-linear vibration problems of continuous mechanical systems [10,11]. However, it should be emphasised that even for linear vibrations of shells with variable thickness numerical results are not so widely presented.…”

“…In practice, these elements can have a variable thickness, different form of the middle surface and boundary conditions, as well as different orientation of the anisotropy axes. The studies of linear vibrations of anisotropic shells have attracted the attention of many researchers for a long time [4,6,7,9,10]. Great progress has been made over the past decades to develop numerical approximate methods as the most effective tools for studying nonlinear vibrations of the composite plates and shallow shells [1-3, 5, 7, 9-11].…”

The present formulation of the analysed problem is based on Donell's nonlinear shallow shell theory, which adopts Kirchhoff's hypothesis. Transverse shear deformations and rotary inertia of a shell are neglected. According to this theory, the non-linear strain-displacement relations at the shell midsurface has been proposed. The validity and reliability of the proposed approach has been illustrated and discussed, and then a few examples of either linear or non-linear dynamics of shells with variable thickness and complex shapes have been presented and discussed.

“…Vibration behaviors of anisotropic OCCSs are analyzed by Selmane and Lakis (1997a;1997b) and Toorani and Lakis (2001). Recently, much attention has been paid to vibration analysis of laminated, composite or functionally graded OCCSs (Qatu, 2002;Singh and Shen, 2005;Qatu et al, 2010;Su et al, 2014;Ye et al, 2014b).…”

Abstract:This paper is concerned with the free vibration analysis of open circular cylindrical shells with either the two straight edges or the two curved edges simply supported and the remaining two edges supported by arbitrary classical boundary conditions. Based on the Donnell-Mushtari-Vlasov thin shell theory, an analytical solution of the traveling wave form along the simply supported edges and the modal wave form along the remaining two edges is obtained. With such a unidirectional traveling wave form solution, the method of the reverberation-ray matrix is introduced to derive the equation of natural frequencies of the shell with different classical boundary conditions. The exact solutions for natural frequencies of the open circular cylindrical shell are obtained with the employment of a golden section search algorithm. The calculation results are compared with those obtained by the finite element method and the methods in the available literature. The influence of length, thickness, radius, included angle, and the boundary conditions of the open circular cylindrical shell on the natural frequencies is investigated. The exact calculation results can be used as benchmark values for researchers to check their numerical methods and for engineers to design structures with thin shell components.

These oscillations can occur from both outside and inside of the building, i.e. from passing automobiles, wind, heating, ventilation and air-conditioning equipment, and these building vibrations effect on laboratory equipment operation as well. The possibility and method of time varying vibration decomposition are discussed in the scientific workof professor Radkowski [11].Honeycomb sandwich structures are currently being used in various engineering solutions, both within and outside of aerospace engineering. Lightweight honeycomb materials can be used in the construction of composite panels, shells, and tubes with high structural efficiency. The dynamic characteristics of Multilayer Polyurethane foam glass/fiber composite sandwich panels have been determined through Experimental Investigations by Havaldar and others [4].Sandwich shell structures including metal alloys and composites are being increasingly applied to many aircraft, automobile and construction industries due to their lightweight and highly load carrying capacities. Furthermore, the use of cellular cores for panels and shells not only can further reduce the structural weight, but also potentially possess superior heat dissipation, vibration control and energy dissipation characteristics. Filament winding and twice co-curing processes were proposed to make a carbon fiber reinforced composite (CFRC) sandwich cylinder with Kagome cores. Axial compression was carried out to reveal the stiffness and load capacity of the fabricated sandwich cylinder. Compared with the stiffened cylinder with similar dimensions and mass, the sandwich cylinder is shown to be stiffer and stronger by several times [3]. Linear and nonlinear analysis using the ABAQUS finite element is described in paper [15]. Some mechanical properties such as compression, bending, impacting and vibration have been reported by many scientists worldwide. Analytical calculation methods have a clear advantage when designing multi-layered composite cylindrical shells. Compared to Finite Element Methods (FEM) they enable more precise physical interpretations and weighting of the different design variables to be made and, hence, significantly facilitate problem-specified parameter studies and sensitivity analysis [5]. Sandwich cylindrical shells are the major components of aerospace apparatus structures [17]. Nevertheless, an analytical investigation was carried out to examine the response of CFRC sandwich cylinders with lattice cores.Researchers Xiong et al [20] manufactured sandwich-walled cylindrical shells with aluminium pyramidal truss core of constant curva-JUREVICIUS M, TURLA V, BUREIKA G, KILIKEVICIUS A.
