APPLICABILITY OF COMPUTATIONAL CELL MODEL FOR NONLINEAR FRACTURE MECHANICS
2005 (English)In: SMiRT 18, 2005Conference paper (Other academic)
In the present report, the applicability of the cell model technique for austenitic stainless steel weld has been investigated. The investigation consists of two parts, an experimental part and a numerical evaluation part. It was found out that the cell model technique accurately captures the fracture process for the standard CT and large size CT specimens.
After the verification, the cell model technique has been applied to predicate the fracture toughness of irradiated (about 0.7 dpa) stainless steel weld. It is shown that the technique can be applied to these materials and thus be of great help in safety analysis of irradiated components in a nuclear power plant.
