A major formulating problem in boundary element method applied to plasticity problem is a singularity of strain incremental formulation at plastic region. This singularity arises from the singularity of Kernel stress derivative and it is a second order singularity. Brebbia, et al.  presents a method to solve the second order singularity problem by expanding the singular integral to reduce to non-singular integral. This method is supported by Kane . Telles and Brebbia  also proposed indirect method to solve hypersingular integral. By using transformation method, and combine with Guiggiani and Gigante work , Leitao  extended Brebbia, et al. works to solve the second order singularity problem. The previous methods to solve the second order singularity problem require further improvement. This paper proposed a new and improved technique to solve this type of problem.
