Abstract
With the aid of the basic theorem of the Fourier cosine transform and Fourier sine series, the general solution of the dynamic stress intensity factor of a finite rectangular plate containing a pair of edge cracks excited by a normal anti-plane shear wave is found in the present paper. We can easily verify that the problems of a strip with a pair of edge cracks subjected to a normally incident anti-plane shear wave are the special cases of the general solution in this article. Especially, it is of interest to note that all of the solutions to the dynamic stress intensity factor of the subject are identical with those results in the paper by the author and Ma ( Engng Fracture Mech. 30, 211–218, 1988).
