Application of the FETI Domain Decomposition Method to Semicoercive Contact Problems

Original language description

The solution to contact problems between solid bodies posesdifficulties to finite element systems because neither the distributions of thecontact tractions throughout the surface areas currently in contact normutual positions of these areas are known a priori until we have runthe problem. These salient features of general contact problems imply thatthe contact inherently is strongly nonlinear.One of new methods which can successfully be applied to solutionto contact problems is the FETI (Finite ElementTearing andInterconnecting) method, which is based on decomposition of aspatial domain into a set of totally disconnected non-overlappingsub-domains. Its novelty consists in the fact that the Lagrangian multipliers,or forces in this context, were introduced to enforce the compatibilityat the interface nodes. They are also called the dual variables in contrast tothe primal variables, which are nodal displacements with the displacementbased finite element analysis.By eliminating the primal
