Application of the Local Approach for Prediction of Ductile Fracture of Highly Irradiated Austenitic Steels

摘要：

　　The physical-and-mechanical model of ductile fracture has been developed to predict fracture toughness and fracture strain of irradiated austenitic steels taking into account stress-state triaxiality and irradiation swelling.Comparison of experimental data on fracture strain of irradiated austenitic weld metal with predicted results by the model has been performed.The model also allows to describe sharp decrease of ultimate strength on the basis of the proposed mechanism called as the running collapse mechanism.
