| Abstract: | A Monte Carlo simulation method was set up for determining the statistics distribution function of fracture toughness JⅠC of welded joint. The statistics distribution function of 316L austenitic stainless steel welded joint JⅠC was obtained by the method. The results shows that the optimal goodness of fit distribution of the JⅠC is a Weibull distribution. The effects of sampling number on results of Monte Carlo simulation were discussed. |
