(2022) A Kriging approach to model updating for damage detection. In: European Workshop on Structural Health Monitoring. EWSHM 2022. Lecture Notes in Civil Engineering, Volume 254, Cham: Springer, pp. 245-255978-3-031-07257-4https://doi.org/10.1007/978-3-031-07258-1_26https://dspace.lib.cranfield.ac.uk/handle/1826/18090For complex or large structures, the model updating process can be long and tedious and numerical methods can be computationally expensive. Hence, practitioners and researchers often resort to meta-modelling techniques when large problems are met. Even so, traditional methodologies, such as the Efficient Global Optimisation, can be slow and give sub-optimal results. This work proposes a new methodology for the model updating of numerical systems based on a novel Kriging approach for the scope of damage detection and quantification. The framework proposed is based on a global-local optimisation strategy recently developed by the authors, the refined Efficient Global Optimisation, herein used to tweak finite element models’ parameters to match the modal data extracted from a numerical system by using the residuals of the modified total modal assurance criterion. The main advantage to existing direct optimisation and meta-modelling frameworks is the more efficient use of computational e ort for higher dimensional problems, which is verified with the use of a numerical system.enUse of archived accepted manuscripts (AMs) of non open-access books and chapters are subject to an embargo period and our AM terms of use, which permit users to view, print, copy, download and text and data-mine the content, for the purposes of academic research, subject always to the full conditions of use.
