Molecular Dynamics Simulation of Double-walled Carbon nanotube Vibrations: comparison with continuum elastic therories
Double-walled carbon nanotubes (DWNTs) are expected to be useful as elements in improving conventional polymer-based fibers and films. An extensive molecular dynamics simulation and continuum analyses are carried out to ...
VIBRATION ANALYSIS OF CURVED SINGLE-WALLED CARBON NANOTUBES EMBEDDED IN AN ELASTIC MEDIUM BASED ON NONLOCAL ELASTICITY
In this paper, the flexural vibration of the curved single-walled carbon nanotube (SWCNT) is investigated, based on the nonlocal Euler-Bernoulli beam model. The SWCNT is assumed to be embedded in an elastic medium. Both ...
Vibrational assignment and structure of Vanadyl acetoacetonate
properties. The aim of present study is to compare the theoretical and experimental results on structure and vibrational analysis of VO(AA)2....
Free vibration analysis of a fully clamped rectangular plate-type nano/micro-resonator in presence of the Casimir force
The Casimir force is resulting from the propagation of retarded electromagnetic waves and acts in sub-micron separations. This force is inversely proportional to the fourth power of the nano/micro-plate’s deflection. Hence, ...
Structure and vibrational analysis of copper (II) heptane-3,5-dione
B-diketonates of different metals have been used in the preparation of some kinds of
catalysts [1,2]. In this study, the structure and vibrational spectra of copper (II) heptane-
3,5-dione, Cu(HPD)2, were ...
Analytical determination of size-dependent natural frequencies of fully clamped rectangular microplates based on the modified couple stress theory
This paper presents an analytical and size-dependent model for vibrational analysis of fully clamped rectangular microplates. Modified couple stress theory (MCST) and the Kirchhoff plate model are considered, and Hamilton’s principle is employed...
Vibration analysis of orthotropic circular and elliptical nano-plates embedded in elastic medium based on nonlocal Mindlin plate theory and using Galerkin method
In the present study a continuum model based on the nonlocal elasticity theory is developed for free vibration analysis of embedded orthotropic thick circular and elliptical nano-plates rested on an elastic foundation. The elastic foundation...
Conformational stability, barriers to internal rotations, and normal coordinate analysis of acetone and its 2H-isotopomers
Abstract: Molecular structure and vibrational spectra of acetone, acetone-d3, and acetone-d6 were investigated by means of ab initio and density functional theory (DFT) calculations. The harmonic and anharmonic vibrational ...
