摘要：

Two energy-release rates due to quasistatic crack propagation in electroelastic materials are obtained by using a Griffith-type energy approach. Their difference represents the free electric field contribution to the propagation of the crack. Appropriate conditions for mechanical and electrical fields allow us to express the energy-release as path independent integrals, already obtained by Pak and Herrmann, and by Maugin and Epstein. Th assumptions are verified on the solution of an antiplane crack problem and the integrals are evaluated in terms of electrical and mechanical stress intensity factors.
