Finite Element Analysis of the Threaded Connections subjected to External Loads

Abstract

Although there are many reports referred to the threaded connections subjected to an external load, no reports have fully investigated the contact surfaces. This paper introduces a numerical method to analyse such cases as the threaded connections subjected to a transverse displacement and the flange coupling under an arbitrary type of load for the typical examples of the threaded connections subjected to external load. And the selfloosening mechanism of the threaded connections and the relation between the axial tension and the external load are discussed by the analytical results.
