Abstract

The results of testing of three rods made of different alloys for creep and long-term strength under normal or tangential stresses, which change once or repeatedly in time, are presented. The kinetic theory of Yu. N. Rabotnov was used as a basis for modeling the obtained data. As a result, a good agreement was obtained between the theoretical characteristics of creep and long-term strength and experimental values.
