Multi-level residue harmonic balance method for nonlinear vibration of the beam
Journal of Low Frequency Noise, Vibration and Active Control, 2022 This study presents the nonlinear vibration and chaotic response of a beam subjected to harmonic excitation. The multi-level residue harmonic balance method is applied to solve the geometrically cubic nonlinear vibration of the simply supported beam. The

Stochastic Viscoelastic Wave Equations with Nonlinear Damping and Source Terms
Journal of Applied Mathematics, 2014 The goal of this paper is to study an initial boundary value problem of stochastic viscoelastic wave equation with nonlinear damping and source terms. Under certain conditions on the initial data: the relaxation function, the indices of nonlinear damping,

Shock 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
Scientific 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.

Nonlinear damping and dephasing in nanomechanical systems
Physical Review B, 2016 We present a microscopic theory of nonlinear damping and dephasing of low-frequency eigenmodes in nano- and micro-mechanical systems. The mechanism of the both effects is scattering of thermally excited vibrational modes off the considered eigenmode.

Nonlinear dynamics of a damped magnetic oscillator [PDF]
Journal of Physics A: Mathematical and General, 1999 We consider a damped magnetic oscillator, consisting of a permanent magnet in a periodically oscillating magnetic field. A detailed investigation of the dynamics of this dissipative magnetic system is made by varying the field amplitude $A$. As $A$ is increased, the damped magnetic oscillator, albeit simple looking, exhibits rich dynamical behaviors ...
