ARTICLE ANNOTATION

quote
The article presents models of elastic-plastic deformation of rods - pipelines under single and cyclic loading, taking into account material damage and interaction with the environment. Based on the deformation theory and the Hamilton-Ostrogradsky variational principle, a system of differential equations for the motion (equilibrium) of rods - pipelines under cyclic loading was obtained. A calculation scheme for underground pipelines under spatial loading, taking into account elastic-plastic interaction, as well as material damage, has been developed. Numerical results for displacement components are presented depending on the number of iterations and loading cycles based on various deformation diagrams. As an illustration, the kinetics of changes in the plasticity zone and material damage are presented.
