The elastic displacement field around a wedge disclination in a semi-finite volume of cylinder is calculated by boundary element method. A plane strain analysis of circular disk was performed and the result was compared with the exact solution of Huang and Mura. It is shown that the displacement boundary condition prescribed on the circumference cannot give any solution close to the exact one, but an additional boundary condition with respect to the wedge-shape strain incompatibility is required in this method of calculation.
