Super Damping of Mechanical Vibrations [PDF]
Scientific Reports, 2019 AbstractWe report the phenomenon of coherent super decay (CSD), where a linear sum of the displacement of several damped oscillators can collectively decay much faster than the individual ones in the first stage, followed by stagnating ones after more than 97% of the energy has been dissipated.

Dynamic characteristics of Mn-Cu high damping alloy subjected to impact load
Advances in Mechanical Engineering, 2021 Mn-Cu high damping alloy is a twin-type damping alloy. Owing to its martensite twin structure at room temperature, it can convert vibration energy into heat energy, thereby reducing vibration.

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 ...

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 ...
