They take into account a history of deformation that allows qualitatively and quantitatively more correctly to describe the effects observed at hot non-stationary deformation of materials. But the linear principle of toting of damages has found more broad application owing to the simplicity and universality. The offered method of definition of parameters of models of accumulation of damages may be a premise of broad application of tensor models for the solution of designer, technological and engineering problems of forecasting (prediction) of durability (longevity), definition of residual resource (safe life) of a toughness of details of machines. The key in the given method is that parameters of models of accumulation of damages are determined on curves of a creep under condition of fixed loading. In the literature huge quantity of data on fixed loading is accumulated, therefore additional experiments for definition of parameters of models of accumulation of damages in most cases to conduct it is not necessary. Reduced in activity experimental inspection of an offered method on the basis of experimental data at hot two-degree deformation of alloy ЭИ826 has confirmed satisfactory adequacy of a method to experimental data.
