VELEZ, WILLIAM; GOMEZ, DANIEL  e  THOMSON, PETER. FINITE ELEMENT MODEL UPDATING: REVIEW. Dyna rev.fac.nac.minas [online]. 2009, vol.76, n.158, pp.177-189. ISSN 0012-7353.

The Finite Element Method is used worldwide as a tool for analyzing the dynamic behaviour of structural systems. However, it is well known that finite element model predictions differ from experimental results obtained from vibration tests carried out on the structures being modelled. The area known in English as Model Updating, or Ajuste de Modelos, as it is called in this document, emerged as a response to the above problem and aims at executing parametric corrections on finite element models in order to make the analytical dynamic properties come closer to their experimental counterparts. This discipline has grown steadily during the last twenty years, although its diffusion in the Latin-American and Colombian context has been poor. This article presents a review of the state of the art at the time of its publication. It is hoped that this work will motivate research on the subject of Model Updating in places different from those where developments in this area have concentrated, and that it will provide sufficient information for Latin-American industries to include this technology in their practice.

Palavras-chave : Model Updating; Finite Element Method; Structural Dynamics; Modal Correlation; Modal Analysis.
