Abstract
AbstractWhile mortar methods are undoubtedly among the most prominent and accurate approaches in computational contact mechanics, they come with considerable cost. The required numerical effort originates not only from the evaluation of the mortar integrals but also from the solution of the system of linear equations within Newton‐type solvers. While each of these cost factors has been analyzed and addressed individually in the past, this contribution outlines approaches and first results to comprehensively reduce the time to solution by combining dynamic load balancing techniques with algebraic multigrid preconditioners. We present a proof of concept for a three‐dimensional unilateral contact simulation with an evolving contact zone.
