Abstract

The correlation between theoretical and experimental models, which takes into account the eigenfrequencies and eigenmodes obtaneid from an eigenvalue problem and experimental modal analysis, permits to match the theorectical and experimental results. Updating aims to modify the structural theoretical model matrices, such as mass and stiffness, to reproduce closely as possible the measured response from the data. A new methodology for updating, based on neural networks, is proposed. The neural network wi
