Effects of Statistical Distribution of Micro-Cracks on Scatter of Fracture Toughness of Steels under Brittle Conditions

Original language description

Aim of the paper is analysis of the effects of statistical distribution of micro-cracks on scatter of fracture toughness of steels under brittle conditions. The results are utilized for reliability assessment of selected functional parts. The reliability considered as a complementary probability of brittle fracture initiation is discussed in dependence on the character of statistical distribution of micro-crack sizes, mechanical properties of steel, mechanisms of energy dissipation during cracks propagation, variation of loading, stress state of functional part and its service life. This probability approach is compared with deterministic reliability access originating from computation of safety factor. Its rational evaluation as a function of acceptable probability of fracture instability provides high economic effects saving materials and energy.
