Three-dimensional elastic analytical programs were developed using the body force method, where the boundaries of an elastic body were approximated with a set of triangular surfaces, and the densities of the body forces were assumed to be constant in each area. Using this method, the necessary integrals could be obtained analytically and CPU time was shortened. Some typical stress concentration problems were analyzed and the results were sufficiently accurate. As a result, it is found that this simple method is available for general stress concentration problems.
