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.

Damping Characteristics of a Novel Bellows Viscous Damper
SensorsMicro-vibrations during the operation of space remote sensing equipment can significantly affect optical imaging quality. To address this issue, a bellows-type viscous damper serves as an effective passive damping and vibration isolation solution.

Viscous damping of perforated planar micromechanical structures [PDF]
Sensors and Actuators A: Physical, 2005 The paper gives an analytical approximation to the viscous damping coefficient due to the motion of a gas between a pair of closely spaced fluctuating plates in which one of the plates contains a regular system of circular holes. These types of structures are important parts of many microelectromechanical devices realized in MEMS technology as ...

Viscous Damping of Vibrations in Microtubules [PDF]
Journal of Biological Physics, 2000 Pokorný et al. have recently suggested that metabolic processes drivemicrotubules in a cell to vibrate at Megahertz frequencies, but the theorydoes not explicitly consider dissipative effects which will tend to damp outthe vibrations. To examine the effects of viscous damping on the structure,we determine viscous forces and rate of energy loss in a ...
