Free vibration analysis of a nonlocal thermoelastic hollow cylinder with diffusion

, 2020
In this article, the constitutive relations and the governing equations are derived for nonlocal thermoelastic solid in the presence of diffusion. The free vibration of a thermoelastic diffusive cylinder is investigated within the framework of the above ...

The Free Vibrations of Grillages

Journal of Applied Mechanics, 1959
Abstract Frequency equations and modal shapes are derived for the transverse vibrations of beam grillages consisting of two sets of equally spaced uniform beams, the mass of the beams and associated plating being taken as lumped at the nodes.

On the Nonlinear Vibrations of Free-Free Beams

Journal of Applied Mechanics, 1971
A nonlinear partial differential equation which describes the natural free-free vibrations of beamlike structures is derived, and then solved approximately by reduction to a nonlinear ordinary differential equation through the use of the Duffing and Ritz-Kantorovich methods.

Free vibration analysis of combined composite laminated cylindrical and spherical shells with arbitrary boundary conditions

Mechanics of Advanced Materials and Structures, 2019
In this paper, the analytical model is established on base of multi-segment partitioning strategy and first-order shear deformation theory. The displacement functions are made up of the Jacobi polynomials along the axial direction and Fourier series ...

Free-Free Vibration Extraction From Available Vibration Data

Recent Advances in Solids and Structures, 2000
Abstract This paper presents a procedure for identifying the free-free vibration data of a structure from the available vibration data of the same structure with boundary conditions. For a structure in a mechanical system, depending upon the dynamic formulation used, we may need a set of free-free modal data or a set of constrained modal
