Semicoercive Contact Problems with Large Displacements by FETI Domain Decomposion Method

Popis výsledku v původním jazyce

One of new methods which can successfully be applied to solution to contact problems is the FETI method which is based on decomposition of a spatial domain into a set of totally disconnected non-overlapping subdomains with Lagrange multipliers enforcingcompatibility at the interfaces. It has turned out to be one of the most successful algorithms for parallel solution of problems described by elliptic partial differential equations. The idea that every individual subdomain interacts with its neighboursin terms of the Lagrangian multipliers can naturally be applied to contact problems. In addition in static cases, this approach renders possible the solution to the semicoercive problems, i.e. the structures with some floating subdomains. The algorithmsstemming from the FETI method were tested in the following numerical experiments:(a) Comparison with the analytical solution to a classic Hertzian problem; (b) Comparison with the analytical solution to contact of a cylinder in a cylindri
