Notes:
The present work deals with an applicability of the local approach to assess in-plane sizeeffects among different sized compact tension (CT) specimens. To characterize ductile crack growthof typical nuclear materials, SA515 Gr.60 and SA516 Gr.70 carbon steels, finite element analysesemploying modified GTN and Rousselier models as well as fracture toughness tests were carried out.Material damage parameters were calibrated using standard CT specimens and reflected to predictfracture resistance (J-R) curves of larger CT specimens. Since comparison results betweennumerically estimated J-R curves and experimentally determined ones corresponded well, it isanticipated that the local approach might be used as a promising tool for ductile fracture evaluationincorporating the in-plane size effect
