An energy approach to evaluation of the subcritical fatigue crack growth periodunder biaxial tension of a plate with an initially rectilinear crack has been proposed. Theinfluence of the change of such external loading parameters as: an angle between the loadingaxes, difference in amplitudes and frequencies, differences in the beginning of cycles (shearby please), difference in loading types (one-long-term static loading, the other – cyclicloading) has been investigated.
