Nonlinear dynamical analysis of an aeroelastic system with multi-segmented moment in the pitch degree-of-freedom
(Elsevier B.V., 2015-01-01)
The effects of a multi-segmented nonlinearity in the pitch degree of freedom on the behavior of a two-degree of freedom aeroelastic system are investigated. The aeroelastic system is free to plunge and pitch and is supported ...
Soliton propagation in a medium with Kerr nonlinearity and resonant impurities: A variational approach
(2003-04-01)
The soliton propagation in a medium with Kerr nonlinearity and resonant impurities was studied by a variational approach. The existence of a solitary wave was shown within the framework of a combined nonintegrable system ...
Interaction of pulses in the nonlinear Schrödinger model
(2003-05-01)
A study was conducted on the interaction of two pulses in the nonlinear Schrodinger (NLS) model. The presence of different scenarios of the behavior depending on the initial parameters of the pulses, such as the pulse ...

Insights on the continuous representations of piecewise-smooth nonlinear systems: limits of applicability and effectiveness
(2021-01-01)
Dynamical systems subject to intermittent contact are often modeled with piecewise-smooth contact forces. However, the discontinuous nature of the contact can cause inaccuracies in numerical results or failure in numerical ...
Dynamical behavior and optimization of a nonlinear vibration absorber
(2016-10-01)
The paper concerns the introduction of cubic nonlinearity into a vibration absorber to improve its effectiveness. The nonlinear stiffness is offered by a thin clamped circular plate which undergoes large flexural deflection. ...
Nonlinear Analysis and Characterization of Piezoaeroelastic Energy Harvesters with Discontinuous Nonlinearities
(2022-01-01)
The effects of freeplay and multi-segmented nonlinearities in the pitch degree of freedom on the dynamical responses of a two-degree-of-freedom piezoaeroelastic energy harvesting system are investigated. The nonlinear ...
Influence of nonlinear effects on the acoustic levitation of small spheres
(IEEEChicago, Illinois, 2014-09-03)
This paper presents the nonlinear characterization of a single-axis acoustic levitator and the analysis of the influence of nonlinear effects on the acoustic levitation of small spheres. First, the nonlinear characterization ...
Non-linear effects on radiation propagation around a charged compact object
(Springer, 2015-10-01)
The propagation of non-linear electromagnetic waves is carefully analyzed on a curved spacetime created by static spherically symmetric mass and charge distribution. We compute how non-linear electrodynamics affects the ...
