Description	Solution of nonlinear problems is in general difficult and expensive. Among nonlinearities we can meet in structural mechanics is the one caused by two or more bodies in contact. This strong nonlinearity is often source of computational difficulties. Our presentation will describe an application of the FETI method to solution of such contact problems in 3D. In addition to the non-linearity caused by the contact between the bodies, we will also consider another non-linearity, namely the large displacements and an algorithm for solution of such problems will be proposed. The numerical experiments will prove efficiency of proposed algorithms comparing them with primal penalty method which appears to be most often used method to solution of mentioned problems.

(en) Řešení nelineárních úloh je obecně složité a výpočetně drahé. Mezi nelinearitami, se kterými se můžeme setkat se vyskytují i ty, teré jsou způsobeny kontaktem dvou nebo více těles. Tato silná nelinearita je zdrojem výpočetní náročnosti. Tento příspěvek popisuje aplikaci FETI metody pro řešení takových kontaktních úloh ve 3D. Mimo nonlinearitu způsobenou kontaktem mezi tělesy budem taktéž uvažovat další nelinearity, jmenovitě pak velká posunutí a navrhneme algoritmus pro řešení těchto úloh. Numerické experimenty prokáží efektivitu navržených algoritmů v porovnání s metodou založenou na primární penaltě, která je nejběžněji používána na řešení uvedených úloh. (cs)
