Nonlinear Damping and Field-aligned Flows of Propagating Shear Alfvén Waves with Braginskii Viscosity

open access: yesThe Astrophysical Journal, 2023
Braginskii magnetohydrodynamics (MHD) provides a more accurate description of many plasma environments than classical MHD since it actively treats the stress tensor using a closure derived from physical principles.

Strong Attractor of Beam Equation with Structural Damping and Nonlinear Damping [PDF]

open access: yesMathematical Problems in Engineering, 2013
This paper is mainly concerned with the existence of a global strong attractor for the nonlinear extensible beam equation with structural damping and nonlinear external damping. This kind of problem arises from the model of an extensible vibration beam.

Noise reduction in a laser by nonlinear damping [PDF]

open access: yesPhysical Review A, 1991
We consider the reduction of the intensity fluctuations in a laser by intracavity nonlinear absorption. The optimum operating conditions for reducing the intracavity intensity fluctuations are not the same as the conditions for reducing the intensity fluctuations in the output field.

Displacement Transmissibility Characteristics of Harmonically Base Excited Damper Isolators with Mixed Viscous Damping

open access: yesShock and Vibration, 2013
The viscous damping force in the mixed form as fd(x˙)=c1x˙+c2|x˙|x˙ can well describe damping characteristics of isolators and dampers in many cases. In this paper, performance characteristics of single-degree-of-freedom (SDOF) linear-stiffness isolators

Identification and modelling of dynamic parameters for round link chains subject to axial loads

open access: yesScientific Reports, 2022
A round link chain subject to axial dynamic loads composes a nonlinear viscoelastic system. Unlike the classical pounding problems, the round link chain will not only suffer linear elastic deformation, but also nonlinear plastic or impacting deformation.

A Study of the Hydrodynamic Performance of a Pitch-type Wave Energy Converter–Rotor

open access: yesEnergies, 2019
The effect of hydrodynamic performance of the wave energy converter (WEC)–rotor based on linear potential flow theory due to nonlinear viscous damping was investigated.

Comparison of Linear and Nonlinear Damping Effects on a Ring Vibration Isolator [PDF]

open access: yes, 2020
Nonlinear isolators in the shape of a circular ring have been shown to have an advantage over linear isolators in that they allow low-frequency vibration isolation.

Nonlinear dynamic stability analysis of Euler–Bernoulli beam–columns with damping effects under thermal environment [PDF]

open access: yes, 2022
In this study, a unified nonlinear dynamic buckling analysis for Euler–Bernoulli beam–columns subjected to constant loading rates is proposed with the incorporation of mercurial damping effects under thermal environment.
