Physical interpretation of the J integral by identifying the associated crack translation.

The physical interpretation of the J integral (i.e., J integral) is clear. J integral is the energy release rate associated with crack extension (i.e., translation of the crack in the x direction). However, the physical interpretation of the J integral remains unclear. In this study, different crack translations in the x direction were selected and tested by calculating the energy release rates associated with the crack translations and comparing them with the theoretical value of the J integral.
