Improving the Accuracy of Analytical Relationships for Mechanical Properties of Permeable Metamaterials

open access: yesApplied Sciences, 2021
Permeable porous implants must satisfy several physical and biological requirements in order to be promising materials for orthopaedic application: they should have the proper levels of stiffness, permeability, and fatigue resistance approximately ...

Effect of boundary conditions and constitutive relations on the free vibration of nonlocal beams

open access: yesResults in Physics, 2020
The free vibrations of nonlocal Euler and Timoshenko beams have been studied extensively, but there still remain some problems concerning boundary conditions and constitutive relations.

Consistency aspects of out-of-plane bending, torsion and shear in a quadratic curved beam element [PDF]

open access: yes, 1990
Curved beams in civil engineering applications call for out-of-plane bending and torsion under the action of13; out-of-plane transverse shear loads. The design of a quadratic displacement curved beam element capable of13; representing shear deformation ...

ON “A CHECK ON THE ACCURACY OF TIMOSHENKO'S BEAM THEORY” [PDF]

open access: yesJournal 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 ...

The cantilever beams analysis by the means of the first-order shear deformation and the Euler-Bernoulli theory

open access: yesTehnički Glasnik, 2019
The effect of the Timoshenko theory and the Euler-Bernoulli theory are investigated in this paper through numerical and analytical analyses. The investigation was required to obtain the optimized position of the pipes support.

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.

Lateral-Mode Vibration of Microcantilever-Based Sensors in Viscous Fluids Using Timoshenko Beam Theory [PDF]

open access: yes, 2014
To more accurately model microcantilever resonant behavior in liquids and to improve lateral-mode sensor performance, a new model is developed to incorporate viscous fluid effects and Timoshenko beam effects (shear deformation, rotatory inertia).
