摘要：
This paper presents a formulation for three-dimensional elasto-dynamics with an elliptic crack based on the Laplace and Fourier transforms andthe convolution theorem. The dynamic stress intensity factor for the crack is deter-mined by solving a Fredholm integral equation of the first kind. The results of thispaper are very close to those given by the two-dimensional dual integral equationmethod.
