In this paper the energy absorption capacity of stiffened circular composite tube is considered. The governing equations and dynamic equilibrium are first derived and then solved. Additionally, a finite element model of reinforced circular composite tube structure is modeled. At the following, the effects of various parameters such as structural geometry, number of rings and stingers on mechani...

A passive jet flow control method for suppressing unsteady vortex shedding from a circular cylinder via a numerical simulation is presented in this paper. The circular cylinder is wrapped in a hollow pipe. There are a set of the suction/jet holes on the windward side and leeward side of the outer surface of the pipe. The oncoming flow enters into the hollow pipe through the inlet holes and then...

This study considers the application of the source-model technique to the solution of the problem of electromagnetic scattering by an arbitrarily shaped dielectric cylinder illuminated by a transient plane wave. The technique is utilised to study the scattering from a dielectric cylinder of circular cross-section and from a cylindrical void of the same cross-section lying in a dielectric medium...

We consider the Rayleigh-Taylor instability problem of two initially stationary immiscible viscous fluids positioned with the denser above the less dense in a finite circular cylinder such that their starting fluid-fluid interface is the horizontal midplane of the cylinder. The ensuing linear instability problem has a 5D parameter space defined by the density ratio, the viscosity ratio, the cyl...

6 The scaled boundary finite-element method (SBFEM) is a novel semi-analytical method 7 developed in the elasto-statics and elasto-dynamics areas that has the advantages of com8 bining the finite-element method with the boundary-element method. The SBFEM method 9 weakens the governing differential equation in the circumferential direction and solves the 10 weakened equation analytically in the ...

In the present study, the author’s previous experimental investigations on the vortex induced vibration of uniform and tapered circular cylinders are numerically simulated. The circular cylinders have medium mass ratios (5.93, 6.1), low mass-damping parameters (0.0275, 0.0279) a mean diameter of 0.028m and an aspect ratio of about 14. A fully coupled two-way fluid-structure interaction (FSI) an...

In the present paper, time dependent creep behavior of hollow circular rotating cylinders made of exponentially graded material (EGM) is investigated. Loading is composed of an internal pressure, a distributed temperature field due to steady state heat conduction with convective boundary condition and a centrifugal body force. All the material properties are assumed to be exponentially graded a...

A fully analytical theory is developed to derive the field diffracted by an infinitely long circular cylinder made of an arbitrary anisotropic homogeneous material, illuminated by an arbitrary plane wave.
