Prediction of crack growth resistance for ductile fracture of neutron-irradiated reactor pressure-vessel steels. part 1

摘要

Theoretical foundations of modeling of the neutron irradiation effect on the level of the upper shelf of the dependence K{sub}(1c)(T) were considered. Modeling involves the application of the local criterion and ductile fracture model suggested by the authors previously. A physical interpretation of the irradiation effect on mechanisms governing ductile fracture was given. Parameters of the model, which are sensitive to the neutron irradiation, were determined.
