A Procedure for the Elastic Stress Analysis of Threaded Connections Including the Use of an Electrical Analogue

摘要

It has been observed that screw threads fail in several ways;however, failures in ductile thread materials clearly indicate that tensile fillet stresses caused by bending rather than shear over the base area of the thread is one of the primary causes of failure. For convenience, the analysis of such connections may be considered as consisting of two phases, namely;(a) evaluation of the load distribution from thread to thread, and (b) evaluation of the tensile fillet stresses in the most severely loaded thread.
