04.2 - Aerostructures Design, Structural Dynamics, AeroelasticityCOMPARING REDUCED ORDER MODEL FORMS FOR NONLINEAR DYNAMICAL SYSTEMSD. Massegur¹, D. Clifford¹, A. Da Ronch¹, S. Symon¹; ¹University of Southampton, United Kingdom This work presents a comparative study between two contrasted ROM approaches: Intrusive against Non-Intrusive techniques. To this aim, a model-based projection method and a machine-learning based system are presented and benchmarked using nonlinear dynamical test cases. Followingly, we perform a thorough performance analysis to highlight the benefits of each approach. |
