| Abstract |
The creep rupture strength of two-connected cross-section rods stretched in an aggressive
medium is investigated. The cross-sections of the rods are considered, in which the shapes of the outer
and inner contours are similar, in addition, the areas of the hollow (inner) part are 25% of the areas of
the bordering outer, loaded part. The areas of the loaded parts of sections with different shapes coincide. To assess the influence of an aggressive medium on creep rupture strength, the Rabotnov kinetic
theory is used. It works with two structural parameters (material damage and concentration of environmental elements in the rod material). To determine the level of an aggressive medium in the rods,
approximate solutions of the diffusion equations are used, based on taking into account the motion of
diffusion fronts from the outer and inner surfaces of the rods. |
