| Abstract: | Based on the endurance test data of high temperature parts, a regression processing has been carried out by using the certain creep rupture extrapolation equation, and then several persistent lifes have been simulated and produced by means of Monte Carlo method and the strong calculating function of MATLAB. On the basis of random dispersivity concerning the persistent life and its statistical behavior, the persistent life of high-temperature pressurized parts and their reliability can be predicted. |
