Abstract This work established the fracture probability equation for JIS SM490A steel using the computational model supported by the local approach and the standard Crack Tip Opening Displacement (CTOD) fracture toughness experiments. As the experime

Critical CTOD is widely used as a fracture toughness parameter for structural steels. Critical CTOD often has a scatter of more than one order of magnitude. To explain this scatter, Beremin proposed a model called Weibull stress or Beremin model, but

The authors propose a new model on cleavage fracture toughness of steels. Fracture toughness of steels is controlled by the weakest link mechanism, so it has intrinsic scatter. Beremin proposed Weibull stress through probabilistic fracture initiation
