Damage detection in nonlinear structures using discrete-time volterra series
(2013-09-16)
Structural damage identification is basically a nonlinear phenomenon; however, nonlinear procedures are not used currently in practical applications due to the complexity and difficulty for implementation of such techniques. ...

Non-parametric identification of a non-linear buckled beam using discrete-time Volterra Series
(2014-01-01)
The consideration of nonlinearities in mechanical structures is a question of high importance because several common features as joints, large displacements and backlash may give rise to these kinds of phenomena. However, ...
Influence of structural nonlinearities in stall-induced aeroelastic response of pitching airfoils
(European Assoc Structural Dynamics, 2014-01-01)
Stall-induced vibrations are a relevant aeroelastic problem for very flexible aero-structures. Helicopter blades, wind turbines, or other rotating components are severely inflicted to vibrate in stall condition during each ...

Identification of nonlinear structures using discrete-time Volterra series
(Abcm Brazilian Soc Mechanical Sciences & Engineering, 2014-05-01)
Mathematical modeling of mechanical structures is an important research area in structural dynamics. The goal is to obtain a model that accurately predicts the dynamics of the system. However, the nonlinear effects caused ...
On the detection of a nonlinear damage in an uncertain nonlinear beam using stochastic Volterra series
(2020-07-01)
In the present work, two issues that can complicate a damage detection process are considered: the uncertainties and the intrinsically nonlinear behavior. To deal with these issues, a stochastic version of the Volterra ...
Nonlinear analysis and bifurcation characteristics of whirl flutter in unmanned aerial systems
(2021-12-01)
Aerial drones have improved significantly over the recent decades with stronger and smaller motors, more powerful propellers, and overall optimization of systems. These improvements have consequently increased top speeds ...
NOnlinearity detection and identification using discrete-time volterra series: Application to a solar array structure
(2015-01-01)
The aim of this paper is to identify a nonlinear model using time responses obtained from a sine sweep excitation applied to a simplif ied solar array structure. The nonlinearity is mainly caused by impacts, gaps and ...
