%X A hybrid model, piezoelectric P-S element, is developed for electroelastic crack analysis. The model is used to investigate coupling crack-tip fields. The obtained numerical solutions recover the 1/√r singularity, and it is in good consistence with the real ones. The results offer a valuable basis for studying the mechanism of coupling fracture.
