Application of r- and hr-adaptive BEM to two-dimensional elastic problem

摘要

This paper presents r- and hr-adaptive boundary element methods. the error analysis is done by the sample point error estimation scheme. Then, the error indicator is defined as the product of the computational errors and the fundamental solutions. Mesh refinement is carried out so that the error indictor distributes almost uniformly on whole boundary elements at the refined mesh. The present method is applied to the two-dimensional elastic problem in order to confirm its validity.
