Nonlinear effects generation in suspended core chalcogenide fibre
(2011-06-15)
In this work we report our achievements in the elaboration and optical characterizations of low-losses suspended core optical fibers elaborated from As2S3 glass. For preforms elaboration, alternatively to other processes ...

Stiffness nonlinearity in structural dynamics: Our friend or enemy?
(2017-04-25)
The effects of nonlinearity, particularly stiffness nonlinearity, has been of concern to structural engineers for many years. Primarily this has been because this type of nonlinearity can cause unpredictable dynamics, and ...
Characterization and interaction of geometric and contact/impact nonlinearities in dynamical systems
(2022-03-15)
In this work, we study how a contact/impact nonlinearity interacts with a geometric cubic nonlinearity in an oscillator system. Specific focus is shown to the effects on bifurcation behavior and secondary resonances (i.e., ...
Effects of combined hardening and free-play nonlinearities on the response of a typical aeroelastic section
(2016-03-01)
This paper presents an investigation about the dynamic response of a three-degree of freedom airfoil with hardening nonlinearity in the pitching stiffness and free-play nonlinearity in the control surface stiffness using ...
On a nonlinear and chaotic non-ideal vibrating system with shape memory alloy (SMA)
(Polish Soc Theoretical & Applied Mechanics, 2008-01-01)
In this paper, we present nonlinear dynamic behaviour of a system which consists of a mass connected to a rigid support by a shape memory alloy (SMA) element and a damper. In order to disturb the system, a DC motor with ...

Investigations on the stability and effectiveness of wing-based piezoaeroelastic systems with combined nonlinearities
(2022-01-01)
An investigation on the effects of the existence of freeplay, polynomial stiffness and aerodynamic nonlinearities on the dynamical responses of flutter-based piezoaeroelastic energy harvesting systems is performed. The ...
On the response at the excitation frequency of a two degrees of freedom nonlinear oscillator
(2017-01-01)
This paper presents an overview of the main theoretical advances and experimental analyses, achieved by the authors in recent years of collaborative research in the field of nonlinear dynamics of coupled oscillators. The ...
