Three slow strain rate tests (SSRT) on one-inch thick-compact tension (IT-CT) specimens, which were fabricated from sensitized 304L stainless steel, were perfbrmed with different extension rates in a simulated boiling water reactor (BWR) environment to derive the environmentally assisted cracking (EAC) growth kinedcs, The crack growth kinetics, depending on the testing conditions, were also described theoretically by Shoji's model, inverse analysis was perfOrmed by fitting the experimental data to the theoretical data to determine the model par raineters ro, which represents a characteristic distance tQ define crack tip strain rate (CTSR).and m, which is a slope of the current decay curve and a function of crack tip water chemistry.Both ro and m can be determined using experimental crack growth data in the analysis. Theoretical CTSR of sensitized 304 stainless steel during constant load line displacement rate tests was calculated using Sheji's model and experimental data of P. Aaltonen et al. The calculation shows that dependences of experimental crack growth rate (CGR) on theoretical CTSR fbr tests under different loading conditions are quite consistent. The theoretical CTSR was also compared to that evaluated using Rice's model under the same experimental conditions, Differences between the two theoretical CTSRs were found and the causes are discussed, lv PVbrds/ Environmentally assisted cracking (EAC), Slow strain rate tests (SSRT), Boiling water reactor (BWR) environment, Crack tip strain rate (CTSR), Theoretical model of EAC
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
