Symmetry preserving algorithm for a dynamic contact-impact problem

Result description

A three dimensional contact-impact algorithm based on the pre-discretization penalty method is presented. It is shown that the proposed method preserves a symmetric treatment of mutually contacting surfaces. The symmetry of the algorithm is tested by a dynamic contact problem when the impact of two cylinders as in the Taylor test is studied. Comparison of the proposed algorithm with the finite element code MARC is made.

    Symetrický kontaktní algoritmus pro řešení dynamických rázových úloh

  • Czech description

    V příspěvku je presentován 3D kontaktní algoritmus založený na pre-diskretizační penaltové metodě. Ukazuje se, že navržená metoda zachovává rovnocenné postavení vzájemně kontaktujících povrchů těles. Tato symetrie algoritmu je ověřena na příkladu rázu dvou válců jako v Taylorově testu a výsledky srovnány s konečnoprvkovým programem MARC.
