Evaluation of the degenerate scale in antiplane elasticity using null field BIE

This paper provides a numerical solution for the degenerate scale in antiplane elasticity using the null field boundary integral equation (BIE). With coordinate transformation, the BIE can be formulated in a normal scale, and a basic solution for the BIE in the normal scale is illustrated. The degenerate scale is easily obtained from the basic solution. Several numerical examples are given.
