    Primal and Dual Penalty Methods for Contact Problems with Geometrical Non-linearities

  • Original language description

    In this paper we are concerned with application of a variant of the FETI domain decomposition method that enforces feasibility of Lagrange multipliers by the penalty. The dual penalty method which has been shown to be optimal for small displacements, isused in inner loop of the algorithm that treats large displacements. We give results of numerical experiments that demonstrate high efficiency of the FETI method with the dual penalty.

    Metoda primární a duální penalty pro řešení kontaktních problémů s geometrickými nelinearitami

  • Czech description

    Článek se zabývá aplikací varianty metody rozkladu oblasti FETI, která vyčísluje Lagrangeovy multiplikátory pomocí penalty. Duální penalta, o které bylo dokázáno, že je optimální pro malé posunutí, je užita ve vnitřní smyčce algoritmu pro řešení velkýchposunutí. Jsou ukázaný výsledky numerických experimentů, které ukazují vysokou účinnost metody FETI s duální penaltou.
