Redukcja macierzy sztywności, mas i tłumienia
The paper deals with the problem of reduction of the stiffness, mass and damping matrices, which are due to the application of the finite element method to solving the dynamic problems of continua. Reduction of the dimensions of the matrices is obtained by means of the finite differences used for constructing the matrices in question.
