| Abstract: | A fatigue-life calculating method--local stress-strain method--is applied to the estimation of the fatigue life of flange in this paper. Its main program is presented in a flow chart and the calculations are also compared with its experiment results. Results show that this method is significant in theory and valuable in engineering application. |
