Application of the Boundary Element Method to Threaded Connection : 2nd Report, In Case of Threaded Connection with Free Flat Boundaries

Abstract

This paper describes the application of the boundary element method to the stress analysis of a threaded connection where there is a large flat unstressed surface, by using the Mindlin solution that enables us to solve the problem involving free flat boundaries without having to discretize those boundaries. The advantage of this method is in its simplicity of giving data as input for concrete problem undertaken by fastener designer in practice. This method make it possible to analyze the axi-symmetric and the three-dimensional problems of a bolted fastener with a contact surface and under service loading, by using the unit partitioning technique.
