摘要：

Two energy approaches to electroelastic fracture yielding path-independent integrals already proposed in the literature are analysed in this paper. A particular problem concerning the propagation of an electrically conducting crack in a dielectric is formulated and the near-tip solution is obtained. This is used to show that one of the above-mentioned energy balances for the fractured body contains a diverging integral, becoming inadequate for the description of such a real situation. The controversy concerning the path-independent integrals is identified as being a controversy between two basic different formulations of electroelasticity equations. In the present context, the obtained results actually represents an argument in favour of the theory that views the action of electromagnetic fields via contact forces rather than at-a-distance forces.
