Stress concentration in a transversally isotropic piezoceramic cylinder near a hyperboloidal neck

The coupled electric and elastic fields near a hyperboloidal neck in a piezoceramic cylinder under static loading are studied. Uniform tensile forces and potential difference are applied to its ends. The dependences of the stress components and the projections of the electric-displacement vector near the neck on the load and the neck curvature are plotted.
