Macierz sztywności i wektor obciążeń superelementu

Józef Wranik
The paper presents the method of forming the stiffness matrix and the load vector for a so-called superelement, that is for an element with a small number of degrees of freedom and of dimensions large in comparison with dimensions of the entire construction. It is shown that the superelement stiffness and its load vector can calculated by a suitable reduction of the general set of equations written for an element with many degrees of freedom.
