Abstract
This lecture gives a brief overview of procedures for validating analytical models using experimental data including some exemplary results. The presentation is restricted to current procedures established by experience with large order industrial applications. The basic numerical techniques for updating the parameters of Finite Element (FE) models are described. Sources of modeling and test data uncertainties are addressed together with related requirements concerning the quality of the initial analytical model and the test data. Obstacles to ensure the prediction capability of the updated models to untested situations are discussed. The described applications include an automotive car body and a civil aircraft structure.
