A study of the variation of fracture toughness Jrc and ductility, measured under both tensile loading and biaxial plane strain (bulge) loading, of AISI 1045 steel in the annealed condition, in the transition temperature range of -60 to 25Β°C was carried out. This temperature range delineates the chan

The fracture toughness of the tempered martensitic stainless steel Eurofer97 has been experimentally characterized in the ductile-to-brittle transition (DBT) region with sub-sized compact tension specimens. The median fracture toughnesstemperature curve in the lower transition region has been found
The model can be expressed by the following formula: in which c is the half length of the major axis, a is the half length of the minor axis, AK,"'/AK,'"' is the ratio of the stress intensity factor at the ends of the major axis to that at the ends of the minor axis. h and n are constants. On the b
