Finite longitudinal vibrations

Proceedings of the Indian Academy of Sciences - Section A, 1947
The theory of Finite Strain gives the interesting result that the differential equation for finite longitudinal vibrations of strings and rods is the same as the general equation for long waves.

Longitudinal vibrations of the relativistic string

Physical Review D, 1978
The question of the existence of longitudinal solutions to the massless relativistic string is addressed. In one space and one time dimension, M/sub 1//sub +/1, the classical string solutions are obtained by explicit construction in terms of step functions. No classical solutions exist with only a finite number of modes.

Analytical Model for Longitudinal Soil Vibration

Journal of Geotechnical Engineering, 1989
An analytical model is derived to provide solutions for longitudinal vibration of soil columns. The model uses a Kelvin‐Voigt element in which the dynamic stresses are the sum of viscous and elastic components. Damping is represented by a viscous damping coefficient that is independent of frequency.

Longitudinal Vibrations of Finite Beams

2015
In Sect. 1.2, the free vibration of a simple mass–spring system was discussed. It was shown that the time dependence of the free vibrations was determined by the natural frequency or eigenfrequency of the system plus the losses.

Longitudinal optical vibrations in vitreous SiO2

AIP Conference Proceedings, 1976
By comparison of Raman and infrared spectra we show that longitudinal vibrational modes account for several of the peaks observed in the first order Raman spectrum of vitreous SiO2. Upon identification of the longitudinal modes, and one defect mode, transverse modes are revealed whose number and position are in good agreement with the predictions of a ...

Longitudinal Circumferential Vibrations of Magnetostrictive Rings

1951
Abstract : An experimental investigation of the longitudinal circumferential vibrations of magnetostrictive rings is the subject of this report. Two methods of exciting several orders of these modes of vibration by means of magnetostriction are described. Sensitivity curves and radiation patterns of experimental transducers operating in these modes are

LONGITUDINAL VIBRATION OF MARINE PROPELLER SHAFTING

Journal of the American Society for Naval Engineers, 1948
Synopsis.Longitudinal vibration of the propeller shafting has been the cause of seizure, serious scoring and excessive wear in the flexible couplings of Naval vessels and has in some cases given rise to unacceptable vibration of the bridge structure.

Longitudinal vibrations of a conical bar

Applied Scientific Research, 1963
The present paper considers longitudinal vibrations of a homogeneous truncated cone. This is probably one of the few cases relating to vibrating rods of variable cross-section, where it is possible to give an exact solution instead of using the well-known laborious approximate procedures.
