Complex Dynamic Phenomena in Circular Cylindrical Shells

Volume 6: Dynamics, Vibration, and Control, 2023
Abstract In this paper the achievements of an intense experimental champaign, regarding shell nonlinear dynamics with and without fluid interaction, with thermal effects, subjected to harmonic or random excitations, is presented. Extreme thermal conditions, and high thermal gradients across the thickness of the shell cause important ...

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 ...

Parametric Instability of Circular Cylindrical Shells

Journal of Applied Mechanics, 1967
Parametric instability of thin, circular cylindrical shells subjected to in-plane longitudinal inertia loading arising from sinusoidal base excitation has been investigated analytically and experimentally. The shell under consideration was rigidly clamped at the base and free at the upper edge.

On Strain-Hardened Circular Cylindrical Shells

Journal of Applied Mechanics, 1960
A consistent kinematic hardening theory termed complete hardening, based on a Tresca initial yield condition, has been applied to determine the general flow laws for rotationally symmetric shells. Representative “long” and “short” cylindrical shell problems with zero axial load are solved using complete hardening and a simpler but approximate kinematic

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
