Abstract

Paper presents the analytical solution of the stress-strain state for a dented pipeline, based on the method of equivalent loads. First off all solution for a harmonic imperfection is found, then using Fourier series expansion a semi-analytical procedure is proposed to assess single dent. Comparison between analytical and numerical results for the axial force and pressure load is given. Influence of the dent dimensions, shell radius to thickness ratio and initial loading to stress concentration factor are discussed.
