respectively. Comparing with J s s with the master curve 2 % bound J c s, denoted as J c(0.02) , J s s were close to, but smaller than J c(0.02) s. From these results, though further studies are necessary, on the point that J s can reproduce the tendency of master curve 2 % bound J c and J s was close to these 2 % bound values, it was concluded that proposed framework in this paper can predict the minimum J c in an engineering sense. The framework has an advantage that J s can be predicted from only tensile test results. 7. Conclusion In this study, engineering framework to predict the minimum J c for a specimen type and thickness from only tensile test results was proposed and validated for 0.5T SE(B) and 1T CT specimen.
