On nonlinear waves in the two-phase piezoelectric powders

摘要

The theoretical approach to the description of the wave propagation and interaction in two-phase powders is proposed. The approach is based on a model of non-linear piezoelastic two-phase mixture, which combines three models: classic theory of quadration nonlinear elasticity, classic electrostatic theory of piezoelasticity and theory of two-phase elastic mixture. Equations obtained describe the interaction of displacement waves of propagation of new electric waves. Plane polarized wave and three standard problems of such eaves propagation have been studied separately and in more detail.
