Comparison of 1D and 2D solutions for a beam under transverse impact
MATEC Web of Conferences, 2018 The problem of non-stationary vibration of an elastic beam caused by a transverse impact loading is studied in this work. In particular, two different approaches to the derivation of analytical solution of the problem are compared. The first one is based

Chaotic Response and Bifurcation Analysis of a Timoshenko Beam with Backlash Support Subjected to Moving Masses [PDF]
International Journal of Railway Research, 2014 A simply supported Timoshenko beam with an intermediate backlash is considered. The beam equations of motion are obtained based on the Timoshenko beam theory by including the dynamic effect of a moving mass travelling along the vibrating path.

Bending evaluation of quintuple-layer FG beams with sliding interactions
Vietnam Journal of MechanicsThis paper introduces a model of a quintuple-layer composite beam made of functionally graded materials (FGMs) and shear connectors. A finite element model is developed using the first-order shear deformation theory (FSDT) of Timoshenko, employing a two-

Comparison of Different Local Unrefined Beam Theories for Bending and Nano Beams Buckling Analysis
Journal of Materials and Engineering Structures, 2016 In this study, non unified local shear deformation theory is proposed to consider the bending and buckling of nano beams. This theory is based on the assumption that the cross-sectional and planar displacements consist of bending and shear components ...

A Study of the Fractal Bending Behavior of Timoshenko Beams Using a Fourth-Order Single Equation
BuildingsIn this paper a new generalized fractal equation for studying the behaviour of self-similar beams using the Timoshenko beam theory is introduced. This equation is established in fractal dimensions by applying the concept of fractal continuum calculus Fα ...
