Free vibration of composite beams including rotary inertia and shear deformation

Composite Structures, 1990
Abstract Exact solutions are presented for the free vibration of symmetrically laminated composite beams. First-order shear deformation and rotary inertia have been included in the analysis. The solution procedure is applicable to arbitrary boundary conditions.

Effects of Rotary Inertia and Shear Deformation on Nonlinear Free Vibration of Microbeams

Journal of Vibration and Acoustics, Transactions of the ASME, 2006
In 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

Effects of rotary inertia shear deformation and non-homogeneity on frequencies of beam

Structural Engineering and Mechanics, 2015
In the present study, separate and combined effects of rotary inertia, shear deformation and material non-homogeneity (MNH) on the values of natural frequencies of the simply supported beam are examined. MNH is characterized considering the parabolic variations of the Young\'s modulus and density along the thickness direction of the beam, while the ...

Effects of shear deformation and rotary inertia on the natural frequencies of axially loaded beams

Journal of Mechanical Science and Technology, 2014
The purpose of this study is to investigate how the axial load in beams influences the relationships between the natural frequencies and the effects of shear deformation and rotary inertia. Four beam theories are considered in this study. Finite element equations of motion for the beams under a tensile load are formulated to allow the application of ...

Shear deformation and rotary inertia effects of vibrating composite beams

Composite Structures, 1992
Abstract Free vibration of symmetrically laminated composite beams is studied based on Timoshenko type equations. Shear deformation and rotary inertia are included in the analysis, but with the term representing the joint action of these effects omitted in the Timoshenko equations. Detailed analytical analysis is performed for the natural frequencies
