| Abstracts: | In this work, the distribution of stress fields in an eccentric pipe under the action of internal pressure is determined in an analytical form. The pipe material was modeled by a medium with hereditarily aging elastoplastic properties. The problem was solved within the framework of the perturbation method. The eccentricity value was taken as a small parameter. The unperturbed state was taken to be the axisymmetric elastoplastic stress state of the pipe, determined taking into account the age and loading history of the material. As a result of modeling, an equation was derived to determine the shape and size of the interface between the elastic and plastic zones in a pipe with eccentricity, and analytical expressions were obtained for the stress components in each of the deformation regions.
