The Transferability of Brittle Fracture Toughness Characteristics.
Original language description
In this paper, the use of the Weibull stress as a measure of the failure probability of cracked body is tested. The Weibull stress model for cleavage fracture of cast steel requires calibration of two micromechanics parameters. Weibull stress seems to bea parameter for prediction of cleavage failure of cracked bodies and the study is focused on the assessment of the effects of constraint loss on cleavage fracture toughness (Jc). To quantify the effects of constraint variation on the cleavage fracture toughness the form of the toughness-scaling model based on the Weibull stress is investigated. Local material parameters have been calculated arising from Beremin approach and calibration is based on the Gao and Ruggieri approach. Method is based on weakest link assumption and incremental fracture probability, which depends not only on the maximum principal stress, but also on the equivalent plastic strain. Accepting this approach to the analysis of local criteria for cleavage fracture th
