The electroelastic problem of the stress state of an electroelastic transversely isotropic medium in which a rigid disk-shaped inclusion is displaced under a load non-centrally applied to its surface is solved exactly. Closed analytical expressions for displacements and stress distributions in the piezoelectric material below the inclusion are derived. The solutions of the static electroelastic equations for a transversely isotropic body represented in terms of harmonic functions are used. The problem is reduced to pair integral equations. Expressions for the stress state of a purely elastic transversely isotropic material with a disk-shaped inclusion under non-central load on its surface the follow from the obtained analytical formulas as partial cases. The effect of the coupling of the mechanical and electric fields on the stress distribution below the rigid inclusion under non-central loading is studied numerically. [ABSTRACT FROM AUTHOR]
