Frequency dispersion of small-amplitude capillary waves in viscous fluids [PDF]
, 2016 This work presents a detailed study of the dispersion of capillary waves with small amplitude in viscous fluids using an analytically derived solution to the initial value problem of a small-amplitude capillary wave as well as direct numerical simulation.

On the interaction of exponential non-viscous damping with symmetric nonlinearities [PDF]
, 2008 This paper studies the interaction between non-viscous damping and nonlinearities for nonlinear oscillators with reflection symmetry. The non-viscous damping function is an exponential damping model which adds a decaying memory property to the damping ...

The role of viscoelastic foundation on flexural gravity wave blocking in shallow water
AIP Advances, 2021 A hydroelastic model is developed to study the interaction of linear long gravity waves with a very large floating flexible plate resting on a viscoelastic foundation, which is based on the Kelvin–Voigt model.

Relativistic r-modes and shear viscosity [PDF]
, 2006 We derive the relativistic equations for stellar perturbations, including in a consistent way shear viscosity in the stress-energy tensor, and we numerically integrate our equations in the case of large viscosity.

Random excitation of a system with bilinear hysteresis [PDF]
, 1960 An analysis is made of the response of a system with bilinear hysteresis to random excitation. It is shown that for moderately large inputs, the additional damping created by the bilinear hysteresis decreases the mean squared deflection compared with ...

Material Damping in Dynamic Analysis of Structures (With LIRA-SAPR Program)
Civil and Environmental Engineering, 2020 The purpose of this paper is to justify that it is necessary to take account of physical and mechanical properties of soil and different materials of erected structure for damping vibrations in dynamic loads; to suggest tools for modelling the damping ...

Viscous damping of r-modes: Large amplitude saturation
, 2012 We analyze the viscous damping of r-mode oscillations of compact stars, taking into account non-linear viscous effects in the large-amplitude regime. The qualitatively different cases of hadronic stars, strange quark stars, and hybrid stars are studied ...

The role of $r$-mode damping in the thermal evolution of neutron stars [PDF]
, 2009 The thermal evolution of neutron stars (NSs) is investigated by coupling with the evolution of $\textit{r}$-mode instability that is described by a second order model.The heating effect due to shear viscous damping of the $\textit{r}$-modes enables us to
