摘要：

<正> In this paper,two kinds of circular crack including external circularcrack and penny-shaped crack in a transversely isotropic piezoelectric space are con-sidered.Firstly,we obtain the solution to the problem of an external circular crack ina transversely isotropic piezoelectric space subjected to antisymmetric normal pointforces and point charges.Based on this,the solution of one-sided loading of an ex-ternal circular crack is constructed.Secondly,the real shape of an external circularcrack and the opening displacement of a penny-shaped crack under an arbitrary pointforce and point charge are further obtained.At last,the results are presented in agraphical form.
