抄録

In a previous paper, in order to improve the accuracy in BEM and FEM, we proposed an expedient method based on the similarity of stress fields near notch roots. In this paper, this method is applied to some three-dimensional BEM problems using constant elements, and its effectiveness is shown. This method enables us to analyze three-dimensional stress concentration problems by coarse meshes.
