Abstract

The transferability of fracture toughness characteristics from point a view of the integrity of components with defects V. Kozak, I. Dlouhy Institute of Physics of Materials, Academy of Sciences of the Czech Republic, Brno, Czech Republic Abstract In this work, the use of the Weibull stress as a measure of the failure probability of cracked body is tested. Fracture of large engineering structures and conventional safety assessment and integrity of components and structures still remains a top field of research in the experimental and the theoretical fracture mechanics. Weibull stress seems to be a parameter for prediction of cleavage failure of cracked bodies and the study is focused to assess the effects of constraint loss on cleavage fracture toughness (JJ. To quantify the relative effects of constraint variation on the cleavage fracture toughness the form of the toughness-scaling model based on the Weibull stress o* is investigated. Local material parameters have been c
