The viscous damping of atmospheric gravity waves

open access: yesCanadian Journal of Physics, 1963
Dissipation produced by viscous damping and thermal conduction is important in the study of atmospheric gravity waves, which are themselves important in a study of "irregular" motions in the upper atmosphere. The mathematics of this damping is considered in some detail here, and charts are given to assess the effects of viscous damping and thermal ...

Equivalent Viscous Damping of Bilinear Hysteretic Oscillators

open access: yesJournal of Structural Engineering, 2015
AbstractAn improved formula to determine the equivalent viscous damping ratio of a single-degree-of-freedom (SDOF) bilinear oscillator is proposed in this paper, which simultaneously considers the influence of the initial period, ductility ratio, and strain hardening ratio.

Hybrid Viscous-Structural Damping Identification Method

open access: yes, 2014
Damping still remains one of the least well-understood aspects of general vibration analysis. The effects of damping are clear, but the characterization of damping is a puzzle waiting to be solved. A major reason for this is that, in contrast with inertia and stiffness forces, it is not clear which state variables are relevant to determine the damping ...
