axial misalignment, angular misalignment, stress concentration coefficient, finite element method, cylindrical shell.

The paper is devoted to the evaluation of the stressed state of the shell containing two common defects in the weld shape – angular and axial misalignment at the same time. Expressions for stress resultants and stress concentration factors for axial and angular misalignment are proposed. The analytical approach is tested by means of numerical calculations for the internal pressure.
