Abstract  In piezoelectric problems, the form of the general solution is dependent on the eigenvalues of the material. The singular stress field and electrical displacement field near the interface edge were deduced in this study. The results showed that the stress field and the electrical displacement field have the same singularity; and that the singularity depends not only on the mechanical properties and shape of the interface edge, but also on the piezoelectric properties of the composite material.

Key words： piezoelectric material      axisymmetric interface edge      singularity      electrical displacement
