Aerospace, 2023 A novel passive vibration-damping device is proposed and investigated for a large deployable solar array. One strategy for achieving high damping in a solar panel is using a yoke structure comprising a hyperelastic shape memory alloy and multiple viscous

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.

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.

Comparative Analysis of Viscous Damping Model and Hysteretic Damping Model
Applied Sciences, 2022 A damping model is one of the key factors in dynamic analysis. Viscous damping and hysteretic damping models are commonly used in structural damping models.

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 ...

Oscillations of weakly viscous conducting liquid drops in a strong magnetic field [PDF]
, 2010 We analyse small-amplitude oscillations of a weakly viscous electrically conducting liquid drop in a strong uniform DC magnetic field. An asymptotic solution is obtained showing that the magnetic field does not affect the shape eigenmodes, which remain ...

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 ...

Sensors, 2018 We established the vibration governing equation for a magnetoelastic (ME) biosensor with target loading in liquid. Based on the equation, a numerical simulation approach was used to determine the effect of the target loading position and viscous damping ...

Vibration Characteristics of Capped Viscous Damping Based on Frame Restoring-Force Amplitude
Frontiers in Built Environment, 2022 This study investigates the performance of several capped viscous damping models which give an upper limit to the initial-stiffness-proportional damping force. The comparing capped viscous damping models are the original and newly proposed one.
