Galerkin least squares finite element method for the obstacle problem
Erik Burman, Peter Hansbo, Mats G. Larson +1
We construct a consistent multiplier free method for the finite element solution of the obstacle problem. The method is based on an augmented Lagrangian formulation in which we eli…

Mixed and stabilized finite element methods for the obstacle problem
Tom Gustafsson, Rolf Stenberg, Juha Videman
We discretize the Lagrange multiplier formulation of the obstacle problem by mixed and stabilized finite element methods. A priori and a posteriori error estimates are derived and…
