... like J integral or stress intensity (BSI, 1999), it is difficult to predict the occurrence of the brittle fracture. A conventional method using Jc gave a conservative prediction of brittle fracture because of the difference of plastic constraint (Minami et al. 1997). The effect of plastic constraint...

... pieces, which was approximately a half of length of the thickness of those, was subjected to high plastic constraint compared to cracks and defects found in welded connections. A conventional method using Jc gave a conservative prediction of brittle fracture (Minami et al. 1997). The plastic constraint...

... assessment of structural components. However, many studies have reported that fracture resistance under mode I loading estimated based on fracture mechanics depends on specimen geometry and size, that is crack-tip plastic constraint ( Toyoda, Minami, Ruggieri, Bessyo, Arimochi and Suzuki , (1994); Kaihara...

Paper Number: ISOPE-I-02-450
.... This inconsistency is brought about due to the difference of stress/strain behaviors depending on plastic constraint in the vicinity of a crack-tip between the fracture toughness testing specimen and the practical structures. Accordingly, the "Transferability" of fracture controlling parameter and the new...
