Numeryczne rozwiązanie problemu drgań własnych na przykładzie płyt

In the paper the method of solution to problems of free vibrations of homogeneous plates with arbitrary boundary conditions has been presented. The applied method of numerical calculations, based on the finite element method, decreases the amount of information remembered by a digital computer to a minimum, thus allowing for solution of the considerable problem of free vibrations. Many elements of the given algorithm may be applied to calculations of free vibrations of other cranes with no other changes.
