A primal-dual active set algorithm for three-dimensional contact problems with ...
Hüeber, Stefan; Stadler, Georg; Wohlmuth, Barbara I.In this paper, efficient algorithms for contact problems with Tresca and Coulomb friction in three dimensions are presented and analyzed. The numerical approximation is based on mortar methods for nonconforming meshes with dual Lagrange multipliers. Using a nonsmooth complementarity function for the 3D friction conditions, a primal-dual active set algorithm is derived. The method determines active contact and f...
