On the dynamic behavior of mono-coupled continuous structures attached to nonlinear springs
(Universidade Estadual Paulista (Unesp), 2021-08-05)
The use of the concept of periodicity has become an interesting solution for structural vibration reduction in many engineering applications. Structures built using the repetitive assembling of identical elements are called ...
Aeroelastic behavior of a wing with a magnetorheological hysteretic model to the damping
(2011)
This paper shows the application of a hysteretic model for the Magnetorheological Damper (MRD) placed in the plunge degree-of-freedom of aeroelastic model of a wing. This hysteretic MRD model was developed by the researchers ...
Numerical Study of a Single-Sided Vibro-Impact Track Nonlinear Energy Sink Considering Horizontal and Vertical Dynamics
(Asme, 2019-12-01)
In this paper, the single-sided vibro-impact track nonlinear energy sink (SSVI track NES) is studied. The SSVI track NES, which is attached to a primary structure, has nonlinear behavior caused by the NES mass moving on a ...
Caracterização experimental de sistemas mecânicos com comportamento não-linear
(Universidade Estadual Paulista (Unesp), 2015-08-20)
A large number of structural engineering designs are seeking for more economic concepts, which leads to lightweight and flexible structures. These structures have nonlinear beha- vior caused by large deformations. In that ...
Three-dimensional formulation of a strain-based geometrically nonlinear piezoelectric beam for energy harvesting
(Sage Publications Ltd, 2021-01)
In this paper, the authors introduce a model of a strain-based geometrically nonlinear piezoelectric beam for modeling energy harvesters. A nonlinear shear-underfomable 3-D Rayleigh’s beam theory is used to model the ...
Nonlinear uncertainty model of a magnetic suspension system
(Pergamon-Elsevier Science Ltd, 2004-11)
The nonlinear identification of a nominal model as well as the uncertainty bounds of a magnetic suspension system is developed. This system has a nonsymmetric dynamic behavior; it has an undershoot but not an overshoot. ...
Method for real-time measurement of the nonlinear refractive index
(American Institute of Physics, 2019-09)
In this work, we propose a novel method for continuous real-time measurement of the dynamics of the nonlinear refractive index n2. This is particularly important for characterizing phenomena or materials (such as biological ...
A piezoelectric beam model with geometric, material and damping nonlinearities for energy harvesting
(IOP Publishing, 2020-09-10)
To predict electrical generation in piezoelectric small-scale beam energy harvesting devices, it is important to have a complete mathematical model that captures the different associated phenomena. In the literature, some ...
