Abstract —Three methods are presented, whereby' static’(R-curve) and fatigue crack growth data may be combined. In the first, a single curve is fitted through both sets of data, making due allowance for residual stresses from prior unloading and stress ratio. For the other two methods, crack growth is divided into tearing and ductile striation formation components. These components may be combined either by adding crack growth rates associated with specified values of stress intensity factor or by adding crack growth resistances associated with specified crack extensions. The results are compared with test data obtained from compact tension specimens of high strength aluminium alloys, BS.L97 (2024–T3) and DTD.5120 (7010–T7651).
