Journal ArticleDOI
Transverse vibrations of a beam elastically restrained at one end and with a mass and spring at the other subjected to an axial force
TL;DR: In this article, the exact solution of the title problem was solved using the classical theory of vibrations of beams and a tabulation of eigenvalues was presented as a function of some of the governing mechanical parameters.
Journal ArticleDOI
Vibrations of an elastically restrained, non-uniform beam with translational and rotational springs, and with a tip mass
TL;DR: In this article, an approximate solution of the title problem is obtained by using the optimized Rayleigh-Ritz approach and it is shown that a simple polynomial co-ordinate function yields accurate fundamental frequency values.
Journal ArticleDOI
Effect of geometric boundary perturbations on the natural frequencies and buckling loads of vibrating clamped circular plates
TL;DR: In this paper, the Galerkin method and Rayleigh's optimization procedure were used to determine the fundamental frequency of vibration and buckling coefficient of clamped circular plates with geometric boundary perturbations.

Journal ArticleDOI
Transverse vibrations of beams with variable moment of inertia and an intermediate support
TL;DR: In this article, the authors used the Ritz method and approximated the deflection function by means of polynomial co-ordinate functions which satisfy the essential boundary conditions, such as the presence of an axial force and concentrated masses.
