This paper uses antiresonant frequencies in the "nite element model updating of an experimental 6-m aluminum truss and analyzes the physical correctness of the updated model by using it to detect damage. Rigid elements are used to simplify the modelling of welded joints, and their dimensions are use

In this paper, a new method of finite element model updating using neural networks is presented. Many previous model updating techniques have exhibited inconsistent performance when subjected to noisy experimental data. From this background it is clear that a successful model updating method must be
Bayesian estimator is a commonly used statistical optimization technique for "nite element model updating. This paper presents a modi"ed Bayesian estimator and discusses its unbiasedness, e$ciency, learning ability and robustness. The main di!erences from other estimators, for instance, the least-sq
Model updating techniques are used to update a "nite element model of a structure so that an updated model predicts the dynamics of a structure more accurately. The application of such an updated model in dynamic design demands that it also predict the e!ects of structural modi"cations with a reason
In this paper, the use of thermoelastic measurements to improve a "nite element model is investigated. The originality of the procedure lies in the use of this stress sum "eld measurement and in the new solution method of the modelling error location stage. Measurement inaccuracies and expansion err
Model updating techniques are used to update a finite element model of a structure so that an updated model predicts more accurately the dynamics of a structure. The application of such an updated model in dynamic design demands that it also predict the effects of structural modifications with a rea
