Correlation of Analysis and Test in Modeling of Structures: Assessment and Review

For any structure, mechanical system or component, an accurate mathematical model is a necessity for the prediction of loads and responses, establishing stability margins, design of control system and integrity monitoring, among other uses. Analytical modeling techniques, even through fairly advanced, possess enough uncertainties to justify testing of the full scale actual structure, or a prototype, in order to verify, improve or optimize an existing analytical model. Test data, or identified parameters, are usually used to identify a dynamic model-mass, stiffness and damping distribution or optimize an existing analytical model.
