Topics and Timetable

The summer school focuses on theoretical and computational aspects of modern interface modeling. Leading experts from France and Germany give an introduction into the fields of fracture and contact mechanics, fatique and failure analysis from a multiscale and multiphysics point of view. Each of the areas needs appropriate solution techniques, like Isogeometric Analysis, the eXtended Finite Element Method, the Mortar method, the Non-intrusive Coupling and the Proper Generalized Decomposition which will be presented as well at the summer school.
