Abstract:
Some issues related to the development of methods for forecasting creep processes are considered. For this purpose, the temporal equivalence principle, temperature-time analogy, stress-time analogy and other analogies and the modern relations between stresses and strains of the hereditary type in the form that allows the possibility of describing plastic deformations are used. The expressions for multiple reduction coefficients are obtained using the time equivalence principle. A brief description of the process using the method of analogies is given. An example of applying the concept of reduced time directly to the creep diagrams is given.
Key words:high-temperature creep, relations between stresses and strains, methods of analogies, temporal equivalence principle, method of forecasting.
