An augmented Lagrangian contact formulation for frictional discontinuities with the extended finite element method

In this paper, an Uzawa-type augmented Lagrangian contact formulation is presented for modeling frictional discontinuities in the framework of the X-FEM technique. The kinematically nonlinear contact problem is resolved based on an active set strategy to fulfill the Kuhn–Tucker inequalities in the n...
