Nonlinear oscillation of circular cylindrical shells

27th Structures, Structural Dynamics and Materials Conference, 1986
The method of multiple scales is used to analyze the nonlinear forced response of circular cylindrical shells in the presence of a two-to-one internal (autoparametric) resonance to a harmonic excitation having the frequency \(\Omega\). If \(\omega_ f\) and \(a_ f\) denote the frequency and amplitude of a flexural mode and \(\omega_ b\) and \(a_ b ...

On an Accurate Theory for Circular Cylindrical Shells

Journal of Applied Mechanics, 1973
The accuracy of the characteristic roots obtained from solving a pair of complex conjugate fourth-order differential equations which govern the deformation of circular cylindrical shells is studied. Roots of the characteristic equations of the pair of fourth-order equations can be readily obtained in simple closed forms, unlike the Flu¨gge and other ...

Nonlinear Supersonic Flutter of Circular Cylindrical Shells

AIAA Journal, 2001
The aeroelastic stability of simply supported, circular cylindrical shells in supersonic flow is investigated. Nonlinearities caused by large-amplitude shell motion are considered by using the Donnell nonlinear shallow-shell theory, and the effect of viscous structural damping is taken into account. Two different in-plane constraints are applied to the

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 ...

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.

On Asymptotic Expansions for Circular Cylindrical Shells

Journal of Applied Mechanics, 1964
The paper presents an asymptotic expansion procedure (with reference to decreasing values of wall-thickness shell-radius ratio) for the solutions of the linear theory of the three simultaneous equations for displacements in isotropic circular cylindrical shells. The resultant expansions are applied to a number of fundamental boundary-value problems for

Nonlinear Dynamics and Stability of Circular Cylindrical Shells

Applied Mechanics, 2004
The nonlinear dynamic response of an imperfect circular cylindrical shell under combined static and dynamic axial load is analyzed. A suitable expansion of the radial displacement, able to describe both buckling and dynamic behaviors is developed; the effect of geometric imperfections is accounted for.

Creep buckling of a circular cylindrical shell.

AIAA Journal, 1969
A theory is presented for the creep behavior and buckling of a circular cylindrical shell under axisymmetrical loads. Elastic deformations and secondary creep are included and the multimembrane model is utilized. The set of differential equations is solved by means of finite difference methods with respect to the axial coordinate and with respect to ...

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.
