Isogeometric analysis and domain decomposition methods

摘要: In the present work we use mortar finite element method for coupling of nonconforming discretized sub-domains in framework nonlinear elasticity. The has been shown to preserve optimal convergence rates (see Laursen (2002) [25] details) and is variationally consistent. We show that can be applied isogeometric analysis with little effort, once NURBS based shape functions implemented. Furthermore, a specific coordinate augmentation technique allows design an energy–momentum scheme constrained mechanical system under consideration. excellent performance redesigned as well illustrated representative numerical examples.
