Abstract

The relevance of the development of analytical methods for the determination of the stressed state of pipelines with differently-thickened compounds is noted. On the basis of shell solutions, an analytical method for determining the basic force and deformation parameters for analyzing the stressed state of pipes with imperfections of transverse welds in the form of axial misalignment is obtained, which simulates common defects in the shape of pipe welding-edge misalignment and thickness change. The numerical simulation for checking the results of analytical analysis showed high convergence of the results in stress concentration zones.
