Calculation of the static creep of heat-resistance materials according to the method of isochrones

The principle of similarity of isochronic curves is sued to devise a unidimensional creep model describing all stages of the process, and the basic experiment is specified. The instantaneous deformation diagram is used as the initial characteristic of the medium in the model. The model describes accelerated creep without making use of the damage function. The creep parameters of heat-resistant materials are calculated in a wide range of temperatures; satisfactory agreement between the theoretical values and experimental data was obtained.Translated from Problemy Prochnosti, No. 2, pp. 40–44, February, 1990.
