Abstract
We consider a Neumann-Neumann Domain Decomposition algorithm associated to a finite element method to approximate a unilateral frictionless contact problem between two elastic bodies. We present a global error estimator that takes into acount as well of the error introduced by finite element analysis as the error committed by the iterative resolution of the domain decomposition algorithm. The control of these errors sources is based on errors indicators that estimate the contribution of each source of error. Numerical results are presented, showing the practical efficiency of the estimator.
