✦ Synopsis
There is confusion in the literature about the boundary condition when crack problems in piezoelectric materials are explored. For example, recently Suo et al.
[1] studied cracks both in piezoelectrics and on interfaces between piezoelectrics and other materials. They used the boundary condition introduced by Deeg [2] and Pak [3] that the normal component of the electric displacement on the crack surfaces disappears, as given by D~ + = D : =0,
