The article contains a complex quantitative evaluation of the effect of the state of stress and of the angle of orientation of the initial crack on its growth rate for eight aluminum alloys subjected to combined modes of biaxial extension. A new dimensionless parameter of fatigue-crack resistance is introduced and substantiated. It is established that there exists a single dependence of the crack growth rate on the suggested parameter for all the investigated aluminum alloys with different mechanical properties.
