Abstract— Imitating Garwood's 3-parameter technique, an experimental parameter Jmax was introduced to predict fatigue crack growth rate (da/dN) over a wide range including small scale yielding and large scale yielding. It was found that for a ΔK-increasing fatigue test condition, Jmax is a valid parameter. A significant crack growth acceleration, caused by a transition of fracture mechanism, occurs when Jmax=JIC The fracture mechanism involving striation formation when Jmax 〈 JIC becomes ductile tearing when Jmax 〉 JIC Equations to predict the effect of stress-ratio on Jmax as well as on da/dN are given.
