## Interface Crack Problem for Electroelastic Body

**abstract:**

A two-dimensional crack problem in the Comninou
formulation is investigated for a piecewise homogeneous plane. Applying a
special integral representation formula for the displacement vector the
problem is reduced to a system of singular integral equations. The system is
analysed and its solvability is proved using the potential method and the
theory of singular integral equations.
