Abstract
The analytical solution of the stress-strain state for pipe with dent based on the method of equivalent loads is developed. The shape of the dent is given in an analytic smooth function for which a semi-analytical solution is found. As a basic, a harmonic dent is considered, the displacements of which are easily calculated, therefore, forces and moments can be easily found. A solution for a single dent is obtained based on expansion in Fourier series. A comparison of analytical and numerical results for the axial force and pressure load is given. Influence of the dent profile to stress concentration factor is discussed.
