Characterization of Pt n (n = 2-12) clusters through global reactivity descriptors and vibrational spectroscopy, a theoretical study
(Elsevier Science, 2012-02)
Geometric, magnetic and electronic features, vibrational frequencies and global reactivity descriptors of Pt n (n = 1-12) were studied in the present work within the framework of the density functional theory. Structures ...
Vibration analysis of rotating Timoshenko beams by means of the differential quadrature method
(Techno-Press, 2010-02)
Vibration analysis of rotating beams is a topic of constant interest in mechanical engineering. The differential quadrature method (DQM) is used to obtain the natural frequencies of free transverse vibration of rotating ...
Natural vibrations of anisotropic plates with an internal curve with hinges
(Pergamon-Elsevier Science Ltd, 2017-01)
The objective of this paper is to propose a general algorithm to obtain approximate analytical solutions for the study of the free vibrations of a rectangular anisotropic thin plate with an internal curved line hinge and ...
Experimental study of the vibrational spectra of (CH3) 3GeBr supported by DFT calculations
(John Wiley & Sons Ltd, 2009-03)
The infrared and Raman spectra of bromotrimethylgermane (BTMG) were recorded afresh to complete the assignment of its vibrational spectra. The vibrational spectrum of BTMG has been predicted from hybrid density functional ...
Free vibrations of AFG cantilever tapered beams carrying attached masses
(Techno-Press, 2017-03)
The free transverse vibrations of axially functionally graded (AFG) cantilever beams with concentrated masses attached at different points are studied in this paper. The material properties of the AFG beam, consisting of ...
Free Vibrations of a Trapezoidal Plate with an Internal Line Hinge
(Hindawi Publishing Corporation, 2014-02)
This paper deals with a general variational formulation for the determination of natural frequencies and mode shapes of free vibrations of laminated thin plates of trapezoidal shape with an internal line hinge restrained ...
Bonding and vibrations of CHxO and CHx species (x=1–3) on a palladium nanoparticle representing model catalysts
(Elsevier Science, 2011-04-11)
This computational study deals with the adsorption of CH3, CH2, CH, CH2OH, CH3O, CH2O and CHO species on a nanoparticle Pd79 that mimics experimentally investigated model Pd catalysts. We quantify structural, energetic and ...
Influence of the nonlocal parameter on the transverse vibration of double-walled carbon nanotubes
(De Gruyter, 2015-10)
A high-order nonlocal continuum beam model is proposed, which can be applied to study the transverse vibrations of double-walled carbon nanotubes (DWCNTs), including those that could have initial deformations due to defects ...
