The problem of an anti-plane Griffith crack moving along the interface of dissimilarpiezoelectric materials is solved by using the integral transform technique.It is shown from the resultthat the intensity factors of anti-plane stress and electric displacement around the crack tip are depen-dent on the speed of the Griffith crack as well as the material coefficients.When the two piezoelectricmaterials are identical,the present result will be reduced to the result for the problem of an anti-planemoving Griffith crack in homogeneous piezoelectric materials.
