Abstract
The normalization method has been employed to estimate the J–resistance ( $$J{-}R$$ ) curves for C-shaped outside edge-notched compression (COEC) specimens of SA-508 steel. The COEC specimens present the lowest $$J{-}R$$ curves in comparison with other three types of specimens. Based on the $$J{-}Q{-}M$$ method, the constraint parameter Q determined at the mid-plane in the through-thickness direction of the specimen is used to approximately quantify the three-dimensional crack-tip constraint for COEC specimens. Combining with the previous experiments on $$J{-}R$$ curves, the constraint-corrected $$J{-}R$$ curves for SA-508 steel specimens are given, which may be used to predict the fracture toughness of actual cracked components in structural integrity assessment.
