| Abstract: | The fracture mechanics of piezoelectric solids is studied. A new electric boundary condition is proposed, in which the electric permeability of air in a crack gap is considered. An exact solution to this problem is given and some numerical results are obtained. It is found that the electric permeability of air in a crack gap leads to a value of KVI less than that of an impermeable crack. |
