Description of known experimental data on the creep rupture strength of tensile rectangular and circular cross-sections rods at high temperature in air media is considered. Simulation of the creep rupture strength of tensile specimens is based on the Yu. N. Rabotnov's kinetic theory with two structural parameters — damage and concentration of the chemical elements of the medium in the rod's material. It has been shown on the basis of experimental data that the scale effect and in particular the relative volume fraction of the surface layer of the rod exposed to the aggressive medium influence on the characteristics of creep rupture strength.
Keywords: rod, creep rupture strength, air aggressive media, kinetic theory, damage, rectangular cross-section, circular cross-section.
