A method is developed for approximate calculation of the thermoelastic stress-strain state of a section of a pipeline containing cylindrical and corrugated parts and operating under internal pressure with uniform heating. Determination of the stress-strain state in an approximate formulation is reduced to the calculation of a cylindrical sheel and one half-corrugation on the assumption that all of the half-corrugations are identical. The problem is solved within the framework of the Kirchhoff-Love hypotheses on the basis of equations of the theory of small elastoplastic strains. The method which is developed is used to study the character of the stress-strain state of a shell of revolution modeling a full-scale pipeline section. The calculated results agree well with experimental data.Institute of Mechanics, E. O. Paton Institute of Electric Welding, and Institute of Strength Problems of the Ukrainian Academy of Sciences.
