On conditioning of constraints arising from variationally consistent discretization of contact problems and duality based solvers
Original language description
Variationally consistent approximation of the non-penetration conditions and friction laws was introduced by Wohlmuth as a powerful tool for the effiective discretization of contact problems. This approach is especially useful when the potential contactinterface is large and curved or when non-matching grids are applied. The point of this note is to give bounds on the singular values of the constraint matrices arising from the variationally consistent approximation and to indicate their application inthe analysis of the scalable duality based domain decomposition algorithms for the solution of multi-body contact problems. The theoretical results are illustrated by numerical experiments.
