Free vibration of a paraboloidal shell of revolution including shear deformation and rotary inertia
Thin-Walled Structures, 2010The governing strain-displacement and curvature-displacement equations for paraboloidal shells including shear deformation and rotary inertia are solved for free vibration of closed shells. The finite element method is used to obtain three-dimensional frequency of vibration solutions for a variety of boundary conditions, free, fixed and simply ...

This paper deals with the effect of shear deformation and rotary inertia on the frequencies of flexural vibration of pre-twisted and non-pre-twisted uniform and tapered cantilever beams. The equations of motion are derived and transformed into a set of linear simultaneous algebraic equations by using finite-difference solutions for the derivatives. The

Influence of rotary inertia and shear deformation on acoustic transmission through a plate
The Journal of the Acoustical Society of America, 1975The reflection and transmission of a harmonic acoustic plane wave from a fluid-loaded plate is investigated using the Timoshenko–Mindlin plate equation. In contrast to the classical plate theory, the effects of rotary inertia and shear deformation are included in the Timoshenko–Mindlin theory. The usual acoustic coincidence frequency and angle based on

The effect of rotary inertia and shear deformation on the parametric stability of unsymmetric shafts
Mechanism and Machine Theory, 1978Abstract A study of the s principal directions running in unsymmetric bearings having fixed common principal planes is presented. Inertia and transverse shear deformation effects are included in the analysis and it is shown that new regions of instability are possible.

Abstract Engineers and designers are often faced with the task of selecting materials that minimizes structural weight whilst meeting the required strength and stiffness. In many cases fibre reinforced composites (FRCs) are the materials of choice since they possess a combination of high strength and low density.

Effects of Shear Deformation and Rotary Inertia on the Nonlinear Dynamics of Rotating Curved Beams
Journal of Vibration and Acoustics, Transactions of the ASME, 1990In this investigation a method for the dynamic analysis of initially curved Timoshenko beams that undergo finite rotations is presented. The combined effect of rotary inertia, shear deformation, and initial curvature is examined. The kinetic energy is first developed for the curved beam and the beam mass matrix is identified.

Vibration of cracked rectangular plates including transverse shear deformation and rotary inertia
Computers & Structures, 1993Abstract A numerical method based on the Rayleigh method for predicting the natural frequencies of a rectangular plate with a centrally located crack is presented. The effects of transverse shear deformation and rotary inertia are included by applying the dynamic equivalent of the simplified Reissner theory.

Effects of Rotary Inertia and Shear Deformation on Nonlinear Vibration of Micro/Nano-Beam Resonators
Microelectromechanical Systems, 2005In this paper, the large amplitude free vibration of a doubly clamped microbeam is considered. The effects of shear deformation and rotary inertia on the large amplitude vibration of the microbeam are investigated. To this end, first Hamilton’s principle is used in deriving the partial differential equation of the microbeam response under the mentioned
