MODAL ANALYSIS OF VIBRATIONS OF VISCOELASTIC LAMINATED PLATES

摘要

The characteristic properties of modes of vibrations of two-layerplates, one layer of which is made from duraluminium and the otherone is made from linear vis- coelastic material with high dampinghave been analyzed. It is shown that covering of the plates withdamping materials makes it possible to make lower the level ofdynamical stresses.
