Torsional vibrations of infinite composite poroelastic cylinders

Study of Torsional Vibrations of Composite Poroelastic Spherical Shell-Biot’s Extension Theory

Torsional vibrations of composite poroelastic dissipative spherical shell are investigated in the framework of Biot’s extension theory.Here composite poroelastic spherical shell consists of two spherical shells, one is placed on other, and both are made of different poroelastic materials. Consideration of the stress-free boundaries of outer surface and the perfect bonding between two shells lea...

Torsional Waves in Composite Co-axial Cylinders with Imperfect Interfaces

We consider the propagation of time-harmonic torsional waves in composite bi-material elastic cylinders. The interface between the core and the surrounding cladding is assumed to be imperfect: the tractions are continuous across the interface but the displacement jump is proportional to the stress acting on the interface. For torsional waves, this requires the introduction of a single constant ...

Torsional Vibrations of Nonhomogeneous

ABSTRACT. This paper is concerned with the torsional vibrations of a nonhomogeneous magnetostrictive elastic cylinder. The cylinder is subjected to the action of a circumferential magnetic field produced by an axial current of constant density and the deformation of a magnetostrictive cylinder is produced by a constant longitudinal magnetic field. The frequency equation is determined, and the d...

Longitudinal-Torsional and Two Plane Transverse Vibrations of a Composite Timoshenko Rotor

In this paper, two kinds of vibrations are considered for a composite Timoshenko rotor: longitudinal-torsional vibration and two plane transverse one. The kinetic and potential energies and virtual work due to the gyroscopic effects are calculated and the set of six governing equations and boundary conditions are derived using Hamilton principle. Differential quadrature method (DQM) is used as ...
