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
