Concentration of electroelastic fields in a composite piezoceramic plate with a hole intersecting the interface of materials

A plane problem of electroelasticity is considered for an infinite compound plate with a hole located in both constituents of the plate. The correspon ding boundary value problem is reduced to a system of singular integral equ ations of second hind, which is solved in numerical quadratures. Calculatio n results are presented that describe the concentration of electroelastic f ields near the hole upon action at infinity of the vectors of mechanical st resses and electric field strength.
