研究了压电固体的断裂力学。提出了一种新的电边界条件，其中考虑了裂纹间隙中空气的电渗透性。给出了该问题的一个精确解，并得到了一些数值结果。结果表明，裂纹间隙中空气的电渗透率导致KVI值小于不渗透裂纹的KVI值。
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 ofKVIless than that of an impermeable crack.
