Advanced Topics in Computational Mechanics

Meetings and events
WEBINAR, December 7-9-10, 2020

In this webinar some advanced and highly up-to-date topics in the area of Computational Mechanics will be presented by international leading scientists in the respective fields. The spectrum of topics will cover solid mechanics, fluid mechanics, coupled problems, model reduction, inverse analysis / uncertainty quantification and the combination of machine learning and physics-based modeling. All lecturer will try to start from a basic introductory level for a generally interested audience but will also cover aspects of current scientific interest.
