Critical response of elastic-plastic SDOF systems with nonlinear viscous damping under simulated earthquake ground motions [PDF]
Heliyon, 2019 Multi impulse with constant time interval is used as a representative of a long-duration earthquake ground motion. An analytical expression is derived for the elastic-plastic response of a single-degree-of-freedom (SDOF) model with nonlinear viscous ...

An Enhanced Q-Factor Cantilever Resonator in Viscous Liquids Using Strategic Perforation [PDF]
MicromachinesCantilever resonators immersed in liquids experience significant viscous damping, which degrades the resonator’s quality factor (Q-factor) and lowers the signal-to-noise ratio.

VD-PQ; A Velocity-Dependent Viscous Damping Model for Wave-Structure Interaction Analysis
Journal of Marine Science and Engineering, 2021 For the analysis and design of coastal and offshore structures, viscous loads represent one of the most influential parameters that dominate their response. Very commonly, the potential flow theory is used for identifying the excitation wave loads, while

Monitoring of Liquid Viscosity for Viscous Dampers through a Wireless Impedance Measurement System
Applied Sciences, 2021 Viscous dampers are a type of seismic damping equipment widely used in high-rise buildings and bridges. However, the viscosity of the damping fluid inside the viscous damper will change over time during its use, which significantly reduces the seismic ...

A General Rule for the Influence of Physical Damping on the Numerical Stability of Time Integration Analysis [PDF]
Journal of Applied and Computational Mechanics, 2018 The influence of physical damping on the numerical stability of time integration analysis is an open question since decades ago. In this paper, it is shown that, under specific very general conditions, physical damping can be disregarded when studying ...
