Abstract
We discuss the theoretical background of modeling the influence of neutron irradiation on the upper-shelf level of the \(K_{{\text{I}}c} \left( T \right)\) relation. The modeling involves a local criterion and a model for ductile fracture proposed by the authors earlier. A physical interpretation of the influence of irradiation on the mechanisms that control ductile fracture is presented. The parameters of the model that are sensitive to neutron irradiation are determined.
