Dynamic Stiffness Matrix for a Beam Element with Shear Deformation

open access: yesShock and Vibration, 1995
A method for calculating the dynamic transfer and stiffness matrices for a straight Timoshenko shear beam is presented. The method is applicable to beams with arbitrarily shaped cross sections and places no restrictions on the orientation of the element ...

Size effect in the bending of a Timoshenko nanobeam

open access: yes, 2017
The size effect should be considered due to the large ratio of surface area to volume when the characteristic length of a beam lies in the nanoscale.

Response of beams resting on viscoelastically damped foundation to moving oscillators [PDF]

open access: yes, 2006
YesThe response of beams resting on viscoelastically damped foundation under moving SDoF oscillators is scrutinized through a novel state-space formulation, in which a number of internal variables is introduced with the aim of representing the frequency ...

Wave propagation characteristics in nanoporous metal foam nanobeams

open access: yesResults in Physics, 2019
This research is devoted to the wave propagation characteristics analysis of nanobeams made of nanoporous metal foams. Three nanoporosity distribution models, namely, symmetry, asymmetry and uniform distributions, are taken into account.

On the Stabilizability of a Slowly Rotating Timoshenko Beam

open access: yesZeitschrift für Analysis und ihre Anwendungen, 2000
In this paper we continue our investigation of a slowly rotating Timoshenko beam in a horizontal plane whose movement is controlled by the angular acceleration of the disk of a driving motor into which the beam is clamped. We show how to choose a feedback control allowing to stabilize our system (the beam plus the disk) in a preassigned position of ...

On Dynamic Properties of Two Models of Beam on Nonlinear Foundation Subjected to Moving Load

open access: yesEngineering Transactions, 1993
The subjects of consideration are the infinite Bernoulli - Euler and Timoshenko models of a beam resting on a nonlinear visco-elastic foundation. The beams are subjected to a distributed inertialess loading constant in a given sector and moving with a ...

Comparing Timoshenko Beam to Energy Beam for fitting noisy data

open access: yes, 2008
In this paper we develop highly flexible Timoshenko beam model for tracking large deformations in noisy data. We demonstrate that by neglecting some physical properties of Timoshenko beam, classical energy beam can be derived. The comparison of these two

Quasi-static Response of a Timoshenko Beam Loaded by an Elastically Supported Moving Rigid Beam

open access: yes, 2019
The present paper is concerned with the quasi-static response of an elastic beam, loaded by a rigid beam, which is slowly transported along the elastic beam. The elastic beam is modelled as a Timoshenko beam. The present paper provides a limiting case of

Frequency spectra of nonlocal Timoshenko beams and an effective method of determining nonlocal effect

open access: yes, 2017
Three critical frequencies independent of boundary conditions together with a critical length, which determine the vibration behaviors of a nonlocal Timoshenko beam, are identified.
