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 ...
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, ...
On the application of discrete-time Volterra series for the damage detection problem in initially nonlinear systems
(2017-01-01)
Nonlinearities in the dynamical behavior of mechanical systems can degrade the performance of damage detection features based on a linearity assumption. In this article, a discrete Volterra model is used to monitor the ...
Updating of a nonlinear finite element model using discrete-time volterra series
(2017-01-01)
In this study, the discrete-time Volterra series are used to update parameters in a nonlinear finite element model. The main idea of the Volterra series is to describe the discrete-time output of a nonlinear system using ...
Structural health monitoring in a buckled beam using Volterra series
(2014-01-01)
This paper proposes a new method to detect damages in structures vibrating with nonlinear behavior. The approach proposed is based on Volterra series and can separate the linear and nonlinear contributions of the responses. ...
Damage detection in uncertain nonlinear systems based on stochastic Volterra series
(2018-01-01)
The damage detection problem in mechanical systems, using vibration measurements, is commonly called Structural Health Monitoring (SHM). Many tools are able to detect damages by changes in the vibration pattern, mainly, ...
