Modern finite element methods (FEM) currently play an important role in the construction, design and development of new materials, innovative products and production processes. Despite successful research in the past, there are still many open problems, e.g., artificial stiffening effects, numerical instabilities and undesired mesh distortion sensitivity. These deficiencies become evident in a wide range of applications in solid mechanics. Within this project, a special focus is on geometrical and material non-linearities, nearly incompressible, anisotropic and generalized materials as well as contact and interface models, since these fields are of great theoretical and practical relevance. Discontinuous Galerkin (DG) methods may be seen as generalizations of continuous methods, thus offering additional features and options for the improvement of numerical computations in the aforementioned fields. This comes at a cost, as DG methods require far more degrees of freedom and memory consumption than continuous discretizations on the same mesh. To improve this issue, we investigate hybrid discontinuous Galerkin methods allowing for a significant reduction
of global degrees of freedom via static condensation.
