Article Preview

This paper adopts contacting finite element method to perform exact stress and strain analysis on bolt joint structure, and the curve of pre-tension stress-life σp-N was drawn. According to the curve, production practice can be well guided and the optimum pre-tension stress may be obtained .By the means of curve between load and deformation, the curve shape of σp-N was analyzed in detail, the results showed that the analysis by finite element was coincident with mechanics analysis.
