Abstract: | The paper establishes the relationship between the solutions of the static contact problems of elasticity (no friction) for
an isotropic half-plane and problems of electroelasticity for a transversely isotropic piezoelectric half-plane with the boundary
perpendicular to the polarization axis. This allows finding the contact characteristics in the electroelastic case from the
known elastic solution, without the need to solve the electroelastic problem. The contact problems of electroelasticity for
different types of wedge-shaped punches (flat punch with rounded one or two edges, half-parabolic punch, and a periodic system
of punches) are solved as examples
