摘要：

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 K-VI less than that of an impermeable crack.
