STUDY ON FRACTURE ASSESSMENT (3RD REPORT); STUDY ON APPLICABILITY OF CTOD DESIGN CURVE

Wide plate tests with stress concentration using 2-dimensional finite element analysis were carried out, and it was shown that the relationship between CTOD and local strain was varied with the relative size of the plastically deformed region as compared with defect size. If the plastically deformed region size was larger than 4 times the crack length, the modified CTOD design curve under- estimates the CTOD value. It is shown that the proposed modified CTOD design curve is valid for fracture strength assessment of cracks in the stress concentrated region except in the above mentioned case.
