The paper aims at presentation of the numerical model of shakedown analysis based on the direct and indirect versions of boundary element method. Comparsion of numerical results with those obtained by the finite element and finite difference methods proved the efficiency and reliability of the boundary elements. A posteriori error estimate and adaptive meshing are discussed and proposed as further improvement of the BEM shakedown analysis.

W artykule opisano model numeryczny służący do rozwiązywania zagadnień dostosowania się ciał sprężysto-plastycznych do obciążeń cyklicznych. Zastosowano pośrednią i bezpośrednią wersję metody elementów brzegowych. Wyniki obliczeń numerycznych porównano z otrzymanymi przy pomocy metod elementów i różnic skończonych. Ich zgodność potwierdza skuteczność i poprawność zastosowanego podejścia. Jako dalsze usprawnienie algorytmu zaproponowano włączenia do algorytmu oszacowania a posteriori błędu obliczeń oraz adaptację siatki.
