Method of strongly singular integral equation for the torision of cylinder with edge crack

From the dislocation type solution of the torsion of single crack, by using the concept of finite part integrals, we reduce the torsion problem of cylinder with a single crack into an integral equation with strong singularity. The numerical method is also obtained and several numerical examples are calculated successfully at the end of this paper. Project supported by P. H. D.
