Bifurcations of a Laminated Circular Cylindrical Shell

International Journal of Bifurcation and Chaos
In this paper, the stability and local bifurcations of a composite laminated circular cylindrical shell with radially pre-stretched membranes are explored by using analytical and numerical methods. On the basis of the four-dimensional averaged equation in the case of 1:1 internal resonance, three types of critical points are studied in detail.

Stability Analysis of Piezoelectric Circular Cylindrical Shells

Journal of Applied Mechanics, 1997
A study on the problem of linear buckling of piezoelectric circular cylindrical shells subjected to external pressure as well as on an electric field is presented. In this paper, the structure is treated as a three-dimensional one. The results reveal that the piezoelectric effect has significant effect on the critical load, while the stress due to the ...

Nonlinear Vibrations of Cantilever Circular Cylindrical Shells

Volume 5: 22nd International Conference on Design Theory and Methodology; Special Conference on Mechanical Vibration and Noise, 2010
Only experimental studies are available on large amplitude vibrations of cantilever shells. In the present paper, large-amplitude nonlinear vibrations of cantilever circular cylindrical shell are investigated. Shells with perfect and imperfect shape are studied.

Analysis of Continuous Circular Cylindrical Shells

Journal of Engineering Mechanics, 1988
In this paper, a procedure to calculate the stress resultants and deformations of continuous cylindrical barrel‐vault shells with edge beams of arbitrary cross section using analytical methods is presented. The procedure is suitable for programming on a microcomputer.

MODAL LOCALIZATION IN VIBRATING CIRCULAR CYLINDRICAL SHELLS

24th International Conference on Sound and Vibration 2017, London Calling
The goal of the present paper is the analysis of the effect of geometric imperfections in circular cylindrical shells. Perfect circular shells are characterized by the presence of double shell-like modes, i.e., modes having the same frequency with modal shape shifted of a quarter of wavelength in the circumferential direction.

Experimental Study on Pre-Stressed Circular Cylindrical Shell

Volume 1: 24th Conference on Mechanical Vibration and Noise, Parts A and B, 2012
In this paper an experimental study on circular cylindrical shells subjected to axial compressive and periodic loads is presented. Even though many researchers have extensively studied nonlinear vibrations of cylindrical shells, experimental studies are rather limited in number.

Dynamic instability of circular cylindrical shells

2005
In the present paper the nonlinear dynamic stability of circular cylindrical shells subjected to dynamic axial loads is investigated. Both Donnell's nonlinear shallow shell and Sanders' theories have been applied in order to evaluate their accuracy. The effect of a contained fluid on the dynamic stability and the postcritical behaviour is analysed in ...

Circular elastic inclusions in cylindrical shells

Computers & Structures, 1978
The problem of a circular elastic inclusion in a cylindrical shell subjected to internal pressure or thermal loading is studied. The two shallow-shell equations governing the behaviour of a cylindrical shell are transformed into a single differential equation involving a curvature parameter and a complex potential function in a non-dimensional form.

The Flexure of a Uniformly Pressurized, Circular, Cylindrical Shell

Journal of Applied Mechanics, 1958
Abstract This paper presents the moment-curvature relationship and the components of displacement in the cross section of a uniformly pressurized, long, closed, circular, cylindrical shell. The shell is loaded in one of its principal planes by two equal and opposite terminal couples: First, the shell undergoes small initial displacements.

Bending of Circular Cylindrical Shells

1960
In the preceding Chapters dealing with the membrane theory of shells, we often met questions which this theory could not answer. This indicates that in certain cases the bending stiffness of the shell, although small, cannot be disregarded and that it is necessary to develop a bending theory.
