| Abstract: | In this paper, the research on the fatigue life of unconventional tubular joints is described. The fatigue loading was calculated though SESAM software. The hot-stress was calculated by finite element method and the analysis of the fatigue life of tubular joints was carried out though S-N curve. Finally, an example of analysis and calculation of the fatigue life of unconventional tubular joints was given to demonstrate that these methods were effective. |
