This thesis is concerned with the devising and the analysis of hybrid discretization methods for nonlinear variational inequalities arising in computational mechanics. Salient advantages of such methods are local conservation at the cell level, robustness in different regimes and the possibility to use polygonal/polyhedral meshes with hanging nodes, which is very attractive in the context of mesh adaptation. Hybrid discretization methods are based on discrete unknowns attached to the mesh faces. Discrete unknowns attached to the mesh cells are also used, but they can be eliminated locally by static condensation. Two main applications of hybrid discretization methods are addressed in this thesis. The first one is the treatment using Nitsche’...
