Abstract

A higher order boundary element, suitable for the body force method (BFM) calculation of 2D or 3D notch problems, is proposed. The interpolation function used in the present element is defined so as to express the exact form of the basic density function in the problem of an elliptic hole under remote load. The availability of the present element in the standing point of the boundary integration for 2D analysis is presented. Some basic 2D and 3D notch problems are solved using standard PC and high accuracy of the present BFM is confirmed.
