【Abstract】 Propagation of a one-dimensional elastic wave through a contact interface between two piezoelectricity solids is analyzed by considering alternation of separation and contact of the interface. Analytical results were presented for the regions of separation and contact and for the coefficients of reflected and refracted waves. The behavior of the harmonics induced by non-linearity is discussed.更多还原
