dcterms:description
An extensive investigation has been carried out on the sensitivity parameters determination describing the fracture behaviour of body with crack with respect to the character change of true stress-strain curve with dominant region of Lueders deformation.Consequently,its convenient substitution has been tested.This paper presents the consideration on the change judgement of J-integral and constraint as the base parameters of two-parameters fracture mechanics.The Weibull stress model for cleavage fracture of cast steel requires calibration of two micromechanics parameters (m,ó u).Weibull stress seems to be a 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 ó w is investigated.Local material parameters have been calculated arising An extensive investigation has been carried out on the sensitivity parameters determination describing the fracture behaviour of body with crack with respect to the character change of true stress-strain curve with dominant region of Lueders deformation.Consequently,its convenient substitution has been tested.This paper presents the consideration on the change judgement of J-integral and constraint as the base parameters of two-parameters fracture mechanics.The Weibull stress model for cleavage fracture of cast steel requires calibration of two micromechanics parameters (m,ó u).Weibull stress seems to be a 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 ó w is investigated.Local material parameters have been calculated arising
