... Reinhardt. 19 10 2013 30 10 2014 21 11 2014 In this paper, the J-R curves of two cracks (A508 HAZ crack 2 and A508/Alloy52Mb interface crack 3) located at the weakest region in an Alloy52M dissimilar metal welded joint (DMWJ) for connecting pipe-nozzle of nuclear pressure vessel...

... of ductile fracture and J-R curve during ductile crack tearing. The recommended test procedure is the elastic unloading compliance method. For a stationary crack, the J-integral is simply calculated from the area under the load-displacement record using the η-factor equation. For a growing crack, the J...

... details of these monotonic tests have been replicated and given in Table 4 . Comparison of the moment versus CMOD curves of displacement controlled cyclic tearing tests and corresponding monotonic test results Comparison of the J - R curves displacement controlled cyclic...

... that the J - R curves for the X80 pipeline steel are strongly constraint dependent. To facilitate transfer of the experimental J - R curves to those for actual cracked components, like flawed pipeline, constraint corrected J - R curves are developed. The two-parameter J - A 2 formulation is adopted...
