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