Energy Release Rate (ERR) Method, its Connection to the J-integral and Extraction of SIFs
The energy release rate in LEFM was given its name by Irwin in 1956 , but was already used in 1920 by Griffith and later shown to be equal to the J-integral by Cherepanov and Rice. In this chapter the various forms of the ERR and their connections are provided.
