The results of the evaluation of distribution structural steels crack resistance characteristics with the use of mathematical statistics based on physically justified distribution laws are
presented in the article. During the work estimated the structural steels of 09G2FB and 16G2SAF
crack resistance characteristics at low temperatures using the criterion of fracture mechanics - stress
intensity coefficient, KCJ are estimated in the article. The results of statistical processing of crack
resistance characteristics are given, the confidence intervals are determined, the functions of distribution are selected and an analysis of selected distributions conformity by criterion of Kolmogorov
- Smirnov is carried out.
