Nonlinear damping in graphene resonators [PDF]

open access: yesPhysical Review B, 2012
Based on a continuum mechanical model for single-layer graphene we propose and analyze a microscopic mechanism for dissipation in nanoelectromechanical graphene resonators. We find that coupling between flexural modes and in-plane phonons leads to linear and nonlinear damping of out-of-plane vibrations. By tuning external parameters such as bias and ac

Effects of Nonlinear Damping on Vibrations of Microbeam

open access: yesApplied Sciences, 2022
The present paper develops a new Bernoulli–Euler theory of microbeams for the consideration of small-scale effects and nonlinear terms, which are induced by the axial elongation of the beam and Kelvin–Voigt damping.

On a Nonlinear Degenerate Evolution Equation with Nonlinear Boundary Damping [PDF]

open access: yesJournal of Applied Mathematics, 2015
This paper deals essentially with a nonlinear degenerate evolution equation of the formKu″-Δu+∑j=1nbj∂u′/∂xj+uσu=0supplemented with nonlinear boundary conditions of Neumann type given by∂u/∂ν+h·, u′=0. Under suitable conditions the existence and uniqueness of solutions are shown and that the boundary damping produces a uniform global stability of the ...

Rogue waves and downshifting in the presence of damping [PDF]

open access: yesNatural Hazards and Earth System Sciences, 2011
Recently Gramstad and Trulsen derived a new higher order nonlinear Schrödinger (HONLS) equation which is Hamiltonian (Gramstad and Trulsen, 2011). We investigate the effects of dissipation on the development of rogue waves and downshifting by adding an ...

Nonlinear Damping Curve Control of Semi-Active Suspension Based on Improved Particle Swarm Optimization

open access: yesIEEE Access, 2022
This paper studies the semi-active suspension damping control algorithm. The shortcomings of traditional damping control algorithms such as the sky-hook algorithm and the acceleration-driven damper algorithms are analyzed in this article.

Nonlinear roll damping of a barge with and without liquid cargo in spherical tanks

open access: yesJournal of Ocean Engineering and Science, 2016
Damping plays a significant role on the maximum amplitude of a vessel's roll motion, in particular near the resonant frequency. It is a common practice to predict roll damping using a linear radiation–diffraction code and add that to a linearized viscous

Dynamic modeling of a non-ideal gyroscopic rotor system with nonlinear damping and nonlinear rigidity of an elastic support

open access: yesAdvances in Mechanical Engineering, 2022
The article considers the effect of joint linear and nonlinear cubic damping on dynamics of a gyroscopic rigid rotor interacting with an electric motor with a rectilinear characteristic, taking into account the nonlinear rigidity of the support material.
