Towards a numerical strategy dedicated to robust design: development and implementation of a multiscale local/global approach taking variabilities and uncertainties into account

The research project aims at taking into account, in the preliminary structural design stages, the impact of uncertainties of structural details on the global architecture, and thus avoid questioning. In this context, we wish to develop novel simulation-based strategies for design, in particular for aeronautics applications. To relate computation and design approaches, and permit the designer to manage the whole set of models at various scales to a priori test the impact of local configurations on the global design, to optimize and validate it, we propose to extend and coupled two families of methods: non-intrusive local/global methods, and methods based on reduced order modeling or learning techniques. The first ones enable the use of the second ones to describe the impact of the response of local components at the global level. The relevance of the proposed approaches will be assessed on realistic industrial applications.
