Detailed stress calculation in selected pipe cross sections.
Stresses are calculated in 48 equidistant points over the circumference at the inner and outer wall side.
|•||neutral top soil weight along pipeline axis|
|•||extra surface loading along pipeline axis|
|•||various subsoil bearing angle functions depending on ratio of subsoil reaction and bearing capacity of the soil, variable along pipeline axis|
|•||lateral horizontal soil support for vertical soil loadings, variable along pipeline axis.|
|•||stress components resulting from internal/external pressure (hoop stress)|
|•||stress components resulting from internal forces, bending and twisting moments in the pipeline, taking into account pressurized toroidal shell behaviour at the pipe bends|
|•||stress components resulting from local soil reactions distributed over the circumference of the pipe cross section, taking into account the "pressurized ring rerounding" effect.|
|•||summation of corresponding stress components|
|•||determination of principal stresses according Mohr's circle|
|•||determination of equivalent stresses according Von Mises/Huber-Hencky yield criterion|
|•||overview of governing stress components and overall stresses.|
|•||overview of governing Mohr, Tresca, Von Mises and uniaxial stresses.|
