Abstract:
In recent years, nonconforming domain decomposition techniques and in particular the mortar method have become popular in developing new contact algorithms. Here, we present an approach for two-dimensional frictionless multibody contact based on a mortar formulation and using a primal-dual active set strategy for contact constraint enforcement. We consider linear and higher order (quadratic) interpolations throughout this work. So-called dual Lagrange multipliers are introduced for the contact p...     »
