Abstract
In the present article, first-order shear deformation theory (FSDT) of the shell has been employed, for the first time, in order to analyze the propagation of the flexural waves in anisotropic fluid-conveying cylindrical shells. Four various anisotropic materials are utilized and their wave propagation behavior surveyed. Viscous fluid flow has been regarded to be laminar, fully developed, Newtonian, and axially symmetric. The Navier–Stokes equation can be utilized to explore the flow velocity effect. FSDT of the shell and Hamilton’s principle have been employed in order to achieve governing equations of anisotropic fluid-conveying cylindrical shells and finally, the obtained governing equations have been solved via an analytical method. In addition, the influences of different variables such as flow velocity, radius to thickness ratio, and longitudinal and circumferential wave numbers have been investigated and indicated within the framework of a detailed set of figures.
Highlights
Shell-type structural elements have been extensively utilized in various modern industries and engineering fields
Tornabene et al [4] studied vibrational responses of thick and moderately-elliptic shells and cylinders made of laminated composite, utilizing the generalized differential quadrature method (GDQM)
Wang and Wu [7] investigated vibrational responses of an functionally-graded materials (FGMs) cylindrical shell considering the effects of porosity and different boundary conditions based on the sinusoidal shear deformation theory
Summary
Shell-type structural elements have been extensively utilized in various modern industries and engineering fields. Analysis of wave propagation in various structures like beam, plate, membrane, and shell, with various materials is one of the most fascinating issues in exploring mechanical behavior. Bouanati et al [38] have studied dynamic and wave propagation characteristics of triclinic and orthotropic plates based upon quasi-3D shear deformation theory. Wave dispersion analysis of multi-scale hybrid nanocomposite circular cylindrical shells to determine the effect of CNT agglomeration on the basis of the FSDT has been performed by Ebrahimi and Seyfi [37]. The wave propagation behavior of anisotropic fluid-conveying cylindrical shells has been surveyed. Various anisotropic materials such as monoclinic, triclinic, trigonal, and hexagonal materials are covered in this paper. The influence of each parameter has been indicated in a group of diagrams that can be seen in future sections
