摘要：

We generalize the energy approach to the evaluation of the residual service life of structural elements under biaxial loading proposed somewhat earlier. On this basis, we construct a mathematical model aimed at the evaluation of the period of subcritical growth of a fatigue crack in the plate subjected to biaxial cyclic loading. The model is used to analyze the influence of the parameters of biaxial cyclic loading on the period of subcritical growth of the fatigue crack.
