This paper deals with applications of the stress and displacement field of twist disclination dipole in the infinite isotropic medium to an analysis of the St. Venant torsion problem by means of indirect boundary element method. The disclination dipole has a singularity at its center so that we introduce the method of fictitious boundary in order to avoid the reduction of accuracy of the analysis which is caused by the singularity. Consequently, it is found that we can obtain sufficient accuracy of the analysis if we choose 3 or more for the coefficient of the distance of the fictitious boundary, and it is ascertained that the fields of the twist disclination dipole can be applied to the analysis of the St. Venant torsion problem.
