Abstract: In this paper, an important transformation formula in the study on the growth of an elliptical crackis derived concisely and exactly, where s is the parameter of Laplace transform, a is constant, k1 and k2 are components of the wavenumber vector k, u and v are rupture propagation velocity along the mutually perpendicular directions, respectively.
