Torsional vibration of cracked carbon nanotubes with torsional restraints using Eringen’s nonlocal differential model

open access: yesJournal of Low Frequency Noise, Vibration and Active Control, 2019
Free torsional vibration of cracked carbon nanotubes with elastic torsional boundary conditions is studied. Eringen’s nonlocal elasticity theory is used in the analysis. Two similar rotation functions are represented by two Fourier sine series.

Pemodelan, Pengujian, Dan Analisis Getaran Torsional Dari Perangkat Uji Sistem Poros-Rotor [PDF]

open access: yes, 2008
Vibrations of rotating machinary can be classified as translational and rotational. The vibrations occurred in rotational direction are commonly classified as torsional vibration. Torsional vibration can cause fatigue damage of shaft, coupling, or gear.

On the Torsional Vibration of Shafting

open access: yesJournal of Zosen Kiokai, 1933
We have had hard experience of many troubles for torsional vibrations in the shafting of Diesel ship; and as a result of available experiments in recent years, the progress of research works in this section is so great, that we can now calculate the critical speeds for torsional vibrations and manage the problems in the design.
