The mathematical model for the contact interaction under the compression of an electroelastic half-space with the elastic isotropic base containing a sloping groove of a circular section was developed. The model takes in account the connectedness of the electroelastic equations system. Two algorithms for solving the problem were proposed, which were based on the representation of solutions of the electroelasticity equations. The analytical problem solution was found, geometrical parameters of clearance between the electroelasticity half-space and deformable base under the known compression were obtained. The influence of connectedness of force and electricity fields on contact parameters of bodies was investigated.
