Essay

Original numerical procedure of calculation of stress strain state of the pipeline in environment is developed. The buckling of the initially straight pipeline in the ideal plastic environment is investigated. The numerical procedure for the solution of geometrical nonlinear Saint Venant's problem for the closed shell with a circular axis is developed. For the first time analytical expression for a stress intensity factors for pipe bend with two longitudinal surface axial cracks is found.
