Mode Shape Analysis of Multiple Cracked Functionally Graded Timoshenko Beams
Latin American Journal of Solids and StructuresThe present paper addresses free vibration of multiple cracked Timoshenko beams made of Functionally Graded Material (FGM). Cracks are modeled by rotational spring of stiffness calculated from the crack depth and material properties vary according to the

Frequency jumps in the planar vibrations of an elastic beam [PDF]
, 2011 The small amplitude transverse vibrations of an elastic beam clamped at both extremities are studied. The beam is modeled as an extensible, shearable planar Kirchhoff elastic rod under large displacements and rotations, and the vibration frequencies are ...

Dynamic Response of a Double-Beam System Subjected to a Harmonic Moving Load
Applied SciencesThe dynamic behavior of a double-beam configuration subjected to a harmonic moving load was studied in this paper. The model was built to represent the wheel–track system that was composed of two infinite Timoshenko beams joined by uniformly spaced ...

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.

Dynamic analysis of laminated composite beam using Timoshenko beam theory
International Journal of Engineering and Advanced Technology, 2019 The uses of laminated composite beams are increasing day by day in many industries. This laminated composite beam has been exposed under different dynamic loadings in mechanical operation. Therefore, the dynamic investigation of laminated composite beams (LCB) is very much necessary to forecast the catastrophe fail of the LCB components.

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 ...
