Micro Abstract:
Finite deformation frictional contact is revisited with a special emphasis on non-smooth geometries such as corners and edges. Contact conditions are enforced separately for point-, line- and surface-contact by employing three different sets of Lagrange multipliers and a variationally consistent discretization approach based on mortar FE methods. In particular, no unphysical transition parameters are required, but all contact decisions are taken implicitly by the underlying solution scheme.
