Abstract
This paper presents a r-adaptive mesh refinement scheme for boundary el- ement methods. Sample point error estimation scheme are applied for the error estimation of the boundary element method. Then, the extended and the global error indicators are defined from the computational errors and the fundamental solutions. Mesh refinement is carried out so that, in the refined mesh, the error indicator distributes uniformly on all boundary elements. The present method is applied to the two-dimensional elastic problem in order to confirm the validity of the present scheme.
