| Abstract: | In this paper,by means of Riemann-Schwarz's symmetry priciple integrated with the analysis singularity of complex potentials,anti-plane problems for the round inclousion with the interfacial cracks of composite piezoelectric materials are investigated,and their complex potential expressions of the electro-elastic field are derived. |
