An analysis of eigenvibrations of piezoelectric plate of AK-cut

An analysis of the AK-cut piezoelectric plate is given regarding an influence of a convex surface shape upon the eigenvibrations. The results extend our first studies and we show how the ratio of radii and direction of main curvature of a piezoelectric plate surface both affect the frequency shifts and amplitude distributions. We notice that the direction of the main curvature causes a substantial influence upon localization of self-vibrations. The dependence in this case is closer to the linear one, although it still needs more profound investigations for the surfaces with different geometries.
