Vibration of non-homogeneous rectangular membranes with arbitrary interfaces
(Academic Press Ltd - Elsevier Science Ltd, 2007-09)
The study deals with the generalized solution of the title problem. The free vibration problem of a rectangular membrane with partial domains each of uniform density and arbitrary interface is tackled. Previous studies by ...
Transverse vibrations of a clamped elliptical plate carrying a concentrated mass at an arbitrary position
(Academic Press Ltd - Elsevier Science Ltd, 2009-03)
Free vibrations of clamped, thin elliptical plates carrying a concentrated mass at an arbitrary position are studied in order to analyze the mass effect on the natural frequencies and mode shapes of the plate. A variational ...

Voltage unbalance and harmonic distortion effects on induction motor power, torque and vibrations
(Elsevier Science Sa, 2016-11)
Voltage unbalance and harmonic voltage distortion affect the power, torque and vibrations on induction motors (IM). In this paper, we compute the frequency of the oscillations of the power, torque and vibrations due to ...
Event generator to construct cross sections for the multiphonon excitation of a set of collective vibrational modes
(American Physical Society, 2010-03)
The construction of differential cross sections as a function of excitation energy for systems with a collection of low- and high-lying intrinsic vibrational modes has been attempted in the past. A prescription is proposed ...
Navier type exact analytical solutions for vibrations of thin-walled shallow shells with rectangular planform
(Elsevier, 2021-03)
Exact analytical solutions for the free vibrations of Thin-Walled shallow shells are presented in this work. The shells considered have rectangular planform and two principal constant curvatures. Past treatment of this ...
Vibrational spectra and theoretical calculations of cis- and trans- 2-thioxohexahydroquinazolin-4(1H)-one towards the interpretation of its thermal reactivity
(Royal Society of chemistry, 2015-04)
FT-Raman and FT-IR spectra of solid cis- and trans- 2-thioxohexahydroquinazolin -4(1H) -one are reported from 4000 to 200 cm-1. The molecular geometry, Wiberg Index, NBO analysis and vibrational wavenumbers in ...
A note on the solution of very basic vibrations problems obtained from a generalised situation
(SAGE Publications, 2005-01-01)
Two forced vibrations problems are fundamental from academic and technological viewpoints; the suddenly applied constant-value force, and the situation where a sinusoidally varying excitation acts on the system. It is shown ...
