Abstract
The stress-strain state and the failure onset time are calculated by Rabotnov's kinetic theory of creep for a thick-walled nonuniformly heated pipe loaded by internal pressure. We analyze the influence of the temperature difference along the pipe radius on the stress intensity distribution and damageability parameter of material in the pipe cross section at various instants of time up to the rupture onset. Based on the comparative analysis, we proved incompatibility of the results obtained by the above-mentioned theory with those calculated by the similar theory of creep in the Kachanov's statement.
