Abstract

Dispersion curves of a
system consisting of a piezoelectric covering layer and metal half-plane under
the uniaxial initial stresses perpendicular to the wave propagation direction
are obtained within the scope of the Three-dimensional Linearized Theory of
Elastic Waves in Initially Stressed Bodies. The elasticity relations of the
metal half-plane material are described by the Murnaghan potential. The
numerical results are discussed for PZT-2 covering layer and aluminum
half-plane material. The influence of the initial stresses, the
piezoelectricity of the covering layer, and the third order elastic constants
on the near-surface wave propagation velocity is illustrated.
