Fatigue analysis of 5-1/2 f.h. threaded connection

摘要

This paper examines the fatigue behavior of the 5-1/2 F.H. threaded connection. The finite element method was used to calculate the static and bending stresses in the pin and box for the purpose of estimating fatigue life of the connection. These stresses were compared with the material properties of the steel and a fatigue life was thereby predicted for a given dogleg.
