Abstract
A bimaterial piezoelectric space with collinear electrically limited permeable cracks along the material’s interface is considered under plane strain conditions. The distances between the cracks, their location and number can be arbitrary. The problem of linear relationship is formulated and solved exactly. The electric flux over the crack regions is found. The closed-form expressions for stresses and electric displacement outside cracks and also for displacement jumps over cracks regions are found. The energy release rates at the crack tips are also derived in an analytical form. Numerical analysis is performed for different loading, cracks permittivity, their number, lengths, and locations.
