This chapter introduces finite-element-model updating. Direct and iterative updating procedures are explained. Some basic features on finite-element modeling are elucidated. Essential elements on vibration testing and analysis are explained and these include the domains in which data can be represented. These domains are in the modal, frequency and time–frequency spaces. Finite-element-model updating techniques are then reviewed and these can be broadly categorized into: matrix update methods, sensitivity-based techniques, iterative optimization procedures, Bayesian methods and computational intelligence techniques. Computational intelligence technques, which are the subject of this book, are then reviewed in detail.
