A justification of the Timoshenko beam model through Γ-convergence
, 2017 We validate the Timoshenko beam model as an approximation of the linear-elasticity model of a three-dimensional beam-like body. Our validation is achieved within the framework of Γ-convergence theory, in two steps: firstly, we construct a suitable ...

Simplified Timoshenko–Ehrenfest beam equation to analyze metamaterials
, 2022 International audienceThis paper is devoted to the incorporation of rotary inertia and shear deformation in the study of acoustic metamaterials. An overwhelming majority of investigators resort to either Bernoulli–Euler or to the Timoshenko–Ehrenfest ...

ON “A CHECK ON THE ACCURACY OF TIMOSHENKO'S BEAM THEORY” [PDF]
Journal of Sound and Vibration, 2002 In a recent article, Rneton (1) presented a comparison between the standing wave natural frequency predictions of Timoshenko beam theory (TBT) for a long beam of thin rectangular cross-section, when the flexural mode is sinusoidal in the axial co-ordinate x, and those of a plane stress elastodynamic solution; the latter may be regarded as the exact ...

Exponential Stabilization for Timoshenko Beam with Distributed Delay in the Boundary Control
Abstract and Applied Analysis, 2013 We consider the exponential stabilization for Timoshenko beam with distributed delay in the boundary control. Suppose that the controller outputs are of the form α1u1(t)+β1u1(t-τ)+∫-τ0g1(η)u1(t+η)dη and α2u2(t)+β2u2(t-τ)+∫-τ0g2(η)u2(t+η)dη; where u1(t)

Vibrations of tapered Timoshenko beams in terms of static Timoshenko beam functions
, 2001 In this paper, the free vibrations of a wide range of tapered Timoshenko beams are investigated. The cross section of the beam varies continuously and the variation is described by a power function of the coordinate along the neutral axis of the beam ...

Rapid Stabilization of Timoshenko Beam by PDE Backstepping
, 2022 In this paper, we present a rapid boundary stabilization of a Timoshenko beam with anti-damping and anti-stiffness at the uncontrolled boundary, by using PDE backstepping.

On the Controllability of a Slowly Rotating Timoshenko Beam
Zeitschrift für Analysis und ihre Anwendungen, 1999 We consider a slowly rotating Timoshenko beam in a horizontal plane whose move-ment is controlled by the angular acceleration of the disk of a driving motor into which the beam is clamped. The problem to be solved is to transfer the beam from a position of rest into a position of rest under a given angle within a given time.
