—Conventionally, fatigue growth rate data are correlated in terms of the range Δ Kof the applied stress intensity factor. It is argued that a correlation involving both Δ Kand the constant stress T close to the tip of the equivalent elastic crack should be adequate for moderate stress, biaxial fatigue data. Practical application of these ideas would involve the preparation of “ T ‐term” compendia similar to those already available for K ‐calibrations. “ T ‐term” data are presented for the case of an edge‐cracked strip in tension.
