... was the mathematical modeling of the system behavior of the pipeline-soil using the finite element method, as implemented in standard program Ansys Mechanical 14.0. Results The calculated values for determining the change of the full longitudinal and equivalent stresses in the wall of offshore pipeline depending on type of pumped-over product, the overlying soil layer and the height of the heaving soil in the frosty heaving of subaqueous permfrost in the coastal zone of the Arctic shelf are given....
