Head Rushchyts'kyj Yarema Yaroslavovych, Доктор фізико-математичних наук Registration Date 22-05-2000 Organization S.P.Timoshenko Institute of Mechanics popup.description2 One is supposed that the piezopowder is a two-phase composite material created by the weak pressing of piezomaterial and led granules. The model of the two-phase piezoelastic mixture is proposed. Basic equations are obtained, which desсribe the wave propagation in mixtures. Nonlinear plane waves are studied. In the assumption of a weak nonlineary, the method of successive approximations is used. Wave effects of the second approximation are analysed.
