Abstract��The relationship between CTOD and J integral were derivated. The formulas 34 of GB/T 21143-2014 was evaluated based on the ASTM E1820-2015 using the CTOD experiments of the three-point bending specimens. It showed that in a small yield range��the CTOD and J integral could be obtained at the same time using the crack opening displacement�� which could simplify the experimental equipment for J integral.
