Finite-Element Updating of the University of Exeter Forum Walkway [PDF]
, 2014 This paper presents the finite element (FE) updating of a walkway, part of the University of Exeter’s Forum building. The walkway is a relatively slender structure with natural frequencies in the range that can be excited by human induced vibrations.

A model updating technique based on FRFs for damped structures [PDF]
, 2012 Model updating methods often neglect that in fact all physical structures are damped. Such simplification relies on the structural modelling approach, although it compromises the accuracy of the predictions of the structural dynamic behaviour.

Model Updating Based on Frequency Response Functions Using A General Finite Element Code [PDF]
, 2003 peer reviewedModel updating techniques using frequency response function (FRF) data are studied in this paper. The numerical techniques are discussed for implementation with a large commercial finite element (FE ) code.

Finite Element Model Updating for Rotary Machinery
, 2016 The main approach of this thesis was to develop a mathematical model that represents a rotary machine. Experimental data was used to define a finite element model (FEM). In order to obtain the experimental data, the rotary machine had to be balanced. An impact hammer test made it possible to obtain frequency response functions (FRF).

A subspace fitting method based on finite elements for fast identification of damages in vibrating mechanical systems [PDF]
, 2012 International audienceIn this paper, a method based on subspace fitting is proposed for identification of faults in mechanical systems. The method uses the modal information from an observability matrix, provided by a stochastic subspace identification ...

Collective motions in globally coupled tent maps with stochastic updating
, 2001 We study a generalization of globally coupled maps, where the elements are updated with probability $p$. When $p$ is below a threshold $p_c$, the collective motion vanishes and the system is the stationary state in the large size limit.

Updating of a Nonlinear Finite Element Model Using Discrete-Time Volterra Series
Latin American Journal of Solids and StructuresIn 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 multidimensional convolutions ...
