Abstract
We determine the electrostressed state of a piezoceramic medium with an arbitrarily oriented triaxial ellipsoidal inclusion under homogeneous mechanical and electric loads. Use is made of Eshelby’s equivalent inclusion method generalized to the case of a piezoelectric medium. Solving the problem for a spheroidal cavity with the axis of revolution aligned with the polarization axis demonstrates the high efficiency of the approach. A numerical analysis is carried out. The stress distribution along the surface of the arbitrarily oriented triaxial ellipsoidal inclusion is studied
