Wave propagation in piezoelectric crystals subjected to intial deformations and electric fields. (English) Zbl 1018.74019
Summary: We study interactions between initial elastic deformations and electric fields in a piezoelectric crystal with respect to the propagation of progressive waves in such crystals. We assume the elastic dielectric to be linear and homogeneous, the initial homogeneous deformations to be infinitesimal, and the initial applied electric field to be of small intensity. For a 6-mm-type crystal, we show that progressive waves can propagate along the symmetry axis, respectively in the plane normal to the symmetry axis.
