Imperfection Sensitivity of Nonlinear Vibration of Curved Single-Walled Carbon Nanotubes Based on Nonlocal Timoshenko Beam Theory. [PDF]
Materials (Basel), 2016 Imperfection sensitivity of large amplitude vibration of curved single-walled carbon nanotubes (SWCNTs) is considered in this study. The SWCNT is modeled as a Timoshenko nano-beam and its curved shape is included as an initial geometric imperfection term

Size-dependent couple stress Timoshenko beam theory [PDF]
arXiv, 2017 In this paper, a new size-dependent Timoshenko beam model is developed based on the consistent couple stress theory. In the present formulation, the governing equations and corresponding boundary conditions are obtained. Afterwards, this formulation is used to investigate size-dependency for several elementary beam problems.

Optimal Profile Design for Acoustic Black Holes using Timoshenko beam Theory [PDF]
, 2022 We revisit the problem of constructing one-dimensional acoustic black holes. Instead of considering the Euler-Bernoulli beam theory, we use Timoshenko's approach instead, which is known to be more realistic at higher frequencies. Our goal is to minimize the reflection coefficient under a constraint imposed on the normalized wave number variation.

Who developed the so-called Timoshenko beam theory? [PDF]
Mathematics and Mechanics of Solids, 2019 The use of the Google Scholar produces about 78,000 hits on the term “Timoshenko beam.” The question of priority is of great importance for this celebrated theory.

Vibrational Energy Flow Analysis of Corrected Flexural Waves in Timoshenko Beam – Part I: Theory of an Energetic Model [PDF]
Shock and Vibration, 2006 In this paper, an energy flow model is developed to analyze transverse vibration including the effects of rotatory inertia as well as shear distortion, which are very important in the Timoshenko beam transversely vibrating in the medium-to-high frequency

The second spectrum of Timoshenko beam theory—Further assessment [PDF]
Journal of Sound and Vibration, 2006 A review of contributions and views on the second spectrum of Timoshenko beam theory (TBT) over the past two decades, together with some new results, are presented. It is shown that the Timoshenko frequency equation factorises not solely for hinged–hinged end conditions, as is often claimed, but also for guided–guided and guided–hinged; these new cases

Extending Timoshenko Beam Theory for Large Deflections in Compliant Mechanisms
Journal of Mechanisms and Robotics, 2022 Compliant Mechanisms (CMs) have presented its inherently advantageous properties due to the fact that the nature of CMs is about utilizing elastic deformation of elementary flexible members to transfer motion, force and energy.

Vibration Analysis of Multilink Manipulators Based on Timoshenko Beam Theory [PDF]
Journal of Robotics, 2011 Timoshenko's theory is adopted in order to accurately describe the freely vibrating dynamics of a multilink flexible manipulator. It is herein presented an analytical modelling strategy that extends previous works through a more refined model which accounts for elastic complicating effects along with lumped inertial loads which are typically mounted on

A Timoshenko beam theory with pressure corrections for layered orthotropic beams [PDF]
International Journal of Solids and Structures, 2011 AbstractA Timoshenko beam theory for layered orthotropic beams is presented. The theory consists of a novel combination of three key components: average displacement and rotation variables that provide the kinematic description of the beam, stress and strain moments used to represent the average stress and strain state in the beam, and the use of exact
