摘要：
First, some path-independent integrals for piezoelectric media are constructed by considering the gradient of the energy stored in deformation and electric field. Secondly, it is proved that one of the path-independent integrals represents the energy release rate when crack extension happens. At last, the expressions are calculated for the mode III problem.
