CIMNE Seminar - "Model reduction of non-linear structural dynamic models: a path in the jungle", by Daniel Rixen
Tuesday, September 19th, 2017. Time: 12h.
Place: O.C. Zienkiewicz Conference Room, C1 Building, UPC North Campus, Barcelona.
Model Reduction techniques for linear structures have been developed since the 60ies and can be considered as fairly mature and established. For non-linear structural models however, reduction approaches are much more recent: several ideas have been proposed and it is hard to keep track of all the different concepts published. It is a jungle! In this presentation we will try to give a structured overview of the different techniques that are currently used or under investigation, starting from the well-known linear reduction techniques and explaining how they can be extended to non-linear systems.
Daniel Rixen, born in 1967, received his engineering degree in Electromechanics and doctoral degree in Applied Sciences from the University of Liège (Belgium). After a post-doctoral stay at the University of Colorado (Center for Aerospace Structures), he was appointed in 2000 as professor on the chair of Engineering Dynamics at the Delft University of Technology (The Netherlands). Since 2012 he leads the chair of Applied Mechanics at the Technical University of Munich (Germany).
His research focuses on the dynamics of mechanical systems and covers the fields of numerical methods, experimental techniques, multiphysics and mechatronics. A significant part of his research involves partitioning problems in order to apply parallel computing, model reduction techniques or experimental substructuring.
