Abstract
The structural material for test blanket module of fusion reactor developed in India is called Indian Reduced Activation Ferritic Martensitic Steel (In-RAFMS). In this study fracture toughness behaviour of In-RAFM steel is investigated using 0.2T bend samples in ductile brittle transition regime. The conventional MC estimates a non-conservative reference transition temperature, T-0, due to Large Scale Yielding (LSY) in small size specimens. Finite element analysis was used to correct the experimental K-JC to equivalent Small Scale Yielding (SSY) values. The numerical approach used in this study is based on critical maximum principal stress (sigma*) - critical stressed volume (V*) method. (C) 2015 Elsevier Ltd. All rights reserved.
