Estimation of J-resistance curves of SA-508 steel from small sized specimens with the correction of crack tip constraint

Based on normalization method, experimental J-resistance (J-R) curves of SA-508 steel using five types of specimen configurations, such as C-shaped outside edge-notched compression (COEC), C-shaped inside edge-notched tension (CIET), miniature single edge notched bend (Mini-SENB), standard SENB and compact tension (CT) specimens are given. Great difference can be observed in these experimental J-R curves because of the various specimen...
