| Abstract: | The problem of an edge crack embedded in the interface of two different piezoelectric materials is analyzed under four cases of combined anti-plane mechanical loads and in-plane electrical loads. The general solution of the electromechanical field, intensity factors and energy release rate are obtained,which are expressed in terms of series expansion. The energy release rate is calculated with the boundary collocation method. It is shown that the method of half analytical and half numeral is simple and widely applicable. |
