Damping of gravitational waves by matter

open access: yes, 2017
We develop a unified description, via the Boltzmann equation, of damping of gravitational waves by matter, incorporating collisions. We identify two physically distinct damping mechanisms -- collisional and Landau damping.

Enhanced gilbert damping in thin ferromagnetic films. [PDF]

open access: yesPhysical Review Letters, 2001
The precession of the magnetization of a ferromagnet is shown to transfer spins into adjacent normal metal layers. This "pumping" of spins slows down the precession corresponding to an enhanced Gilbert damping constant in the Landau-Lifshitz equation ...

Dynamical depinning of chiral domain walls [PDF]

open access: yes, 2017
The domain wall depinning field represents the minimum magnetic field needed to move a domain wall, typically pinned by samples' disorder or patterned constrictions.

Comparison between a traditional Colombian Structural Design and the Use of Viscous-Type Energy Damping Systems (2021)

open access: yesIngeniería e Investigación, 2023
This paper compares a traditional Colombian structural design to the same structure with viscous-type energy dampers, considering both structural behavior and construction costs.

Determining Vibration Frequency and Damping of Metal Beams Using Image Processing Method [PDF]

open access: yesComputational Engineering and Physical Modeling
In the present study, damping and frequency of two beams, including galvanized and steel beams, were evaluated using the image processing method. The beam supports were designed as a hinge and the intended beam was vibrated through displacements. the FFT

On damping created by heterogeneous yielding in the numerical analysis of nonlinear reinforced concrete frame elements

open access: yes, 2015
In the dynamic analysis of structural engineering systems, it is common practice to introduce damping models to reproduce experimentally observed features.

On the robustness of the average power ratios in damping estimation: application in the structural health monitoring of composites beams [PDF]

open access: yes, 2010
In composites structures, cracking, delamination will cause changes in the measured dynamic response of structure and so on experimentally modal parameters.

Production and characterization of thermoplastic elastomer foams based on the styrene–ethylene–butylene–styrene (SEBS) rubber and thermoplastic material

open access: yesOpen Chemistry, 2021
Thermoplastic elastomer foams based on styrene–ethylene–butylene–styrene (SEBS)/polypropylene (PP) were produced by using different processing techniques such as extrusion and injection molding to achieve optimized mechanical and thermal properties in ...
