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.
