Nonlinear updating method: a review
(2017-11-01)
This paper is a survey of the literature about the nonlinear updating process. It is focused on the computation of the difference between the numerical model and the reference data as well as the algorithm uses to find 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 ...
Nonlinear FE model updating of seismic isolated bridge instrumented during the 2010 Mw 8.8 Maule-Chile Earthquake
(Elsevier, 2017)
In this paper, nonlinear finite element model updating (FEMU) is performed to study the prediction accuracy of a state-of-the-art
finite element (FE) model of a seismic isolated bridge (SIB). The seismic isolator model ...
Nonlinear FE model updating and reconstruction of the response of an instrumented seismic isolated bridge to the 2010 Maule Chile earthquake
(Wiley, 2017)
Nonlinear finite element (FE) modeling has been widely used to investigate the effects of seismic isolation on the response of bridges to earthquakes. However, most FE models of seismic isolated bridges (SIB) have used ...
Application of Volterra series in nonlinear mechanical system identification and in structural health monitoring problems
(Universidade Estadual Paulista (Unesp), 2016-03-04)
Nonlinear structures are frequent in structural dynamics, specially considering screwed components, with joints, clearance or flexible components presenting large displacements. In this sense the monitoring of systems based ...
Application of Volterra series in nonlinear mechanical system identification and in structural health monitoring problems

Model updating of the non-linear vibrating structures through Volterra series and proper orthogonal decomposition
(Katholieke Univ Leuven, Dept Werktuigkunde, 2012-01-01)
Classical procedures for model updating in non-linear mechanical systems based on vibration data can fail because the common linear metrics are not sensitive for non-linear behavior caused by gaps, backlash, bolts, joints, ...

Use of state estimation for inferential nonlinear MPC: a case study
(Elsevier Science Sa, 2005-01-28)
Model predictive control (MPC) has become very popular in process industry and academia because it is an optimizing control technique which can handle hard constraints as well as time delays and mild nonlinearities. Linear ...
