Abstract
With the concepts of the confidence interval, a random parameter can be transformed into
an interval number in the mesco ductile fracture. Hence analyses of the random isolated void model
can be used in the interval analysis method. Based on the macro- and mesco-experimental results of
four steels, 30CrMnSiA, 40CrNiMoA, No.45 and No.20, the probabilistic fracture characteristics of
the four steels are given. Finally the interval isolated void models in the four steels are discussed.
