Pipeline Curvature [simulated]

[jeanGiraud]

Mike,

The lspline simulates pretty well the constrained shape of the pipeline. If you have no better maths than that, then you have a problem. The Mathcad b_spline could provide a bit different shape, but again if you don't have the real mathematical model you are back to square 0 ! I leave it to your expertise and your International Consortium. It all resumes to a shape continuous up to the 2nd derivative, whichever the model .

Added the previous sag calculation [jmG]

Jean,

Another fantastic piece of work. Cheers for the time you have spent helping on this project.

Thanks, most appreciated. I can feel what the radius of curvature might represent in terms of "applied strength of materials", but can't analyse as a pure physico-mathematical model.
