Modified beam theories for bending properties of nanowires considering surface/intrinsic effects and axial extension effect [PDF]

, 2012
Several studies of the surface effect on bending properties of a nanowire (NW) have been conducted. However, these analyses are mainly based on theoretical predictions, and there is seldom integration study in combination between theoretical predictions ...

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

, 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).

A fresh study for dynamic behaviour of atomic force microscope cantilever by considering different immersion environments

Journal of Experimental Nanoscience, 2020
In this article, the dynamic behaviour of a rectangular atomic force microscope immersed in different liquids has been investigated. To account the rotatory inertia and shear deformation effects, Timoshenko beam theory has been applied.

Modeling an elastic beam with piezoelectric patches by including magnetic effects

, 2014
Models for piezoelectric beams using Euler-Bernoulli small displacement theory predict the dynamics of slender beams at the low frequency accurately but are insufficient for beams vibrating at high frequencies or beams with low length-to-width aspect ...

Dynamic behavior of a rotating delaminated composite beam including rotary inertia and shear deformation effects [PDF]

, 2015
A finite element (FE) model is developed to study the free vibration of a rotating laminated composite beam with a single delamination. The rotary inertia and shear deformation effects, as well as the bending–extension, bending–twist and extension–twist ...
