On effective implementation of the non-penetration condition for non-matching grids preserving scalability of FETI based algorithms
Original language description
Variationally consistent approximation of the nonpenetration conditions and friction laws was introduced by Wohlmuth as a powerful tool for the discretization of contact problems. This approach is especially useful when the potential contact interface islarge and curved or when nonmatching grids are applied. In this paper we examine how this scheme complies with our recent development of scalable algorithms for contact problems. In particular, we show that the constraint matrices arising from the variationally consistent approximation are well conditioned under natural restrictions and satisfy the assumptions that guarantee the scalability of our algorithms. The theoretical results are illustrated by numerical experiments.
