For accurate results of Ww and Iw (of the pipe wall), the transverse Poisson's ratio may also be taken into account. Ww and Iw should therefore still be multiplied by a factor of 1/(1-ν²).

This would reduce the stress and ovalisation calculations a little bit.

The NEN working group has clarified the correct pipe diameter for the assessment of deflection. For the assessment of ovalisation (vertical deflection and 'piggability') of steel pipes, the new design standard Draft NEN 3650-2:2025 uses the average diameter Dg, see screenshot below. When the NEN 3650-2:2026 code is released end Q2/begin Q3 the sources in PLE needs to be changed everywhere where the ovalisation calculation is used. For the General analysis method the avarage diameter should also be used according to other material NEN 3650 codes then steel (NEN 3650-2).

Highlights of this release:

• The program has been rebranded and is now officially called PLE, with a new logo.
  
• Significant improvements have been made to the calculation of axial buckling and pipe implosion.
  
• The import from secondary database functionality has been overhauled, enabling fine-grained control over which data is imported.

Request 1:
Please add the misssing graphs of the input/output tables from the old theoretical manual of PLE-micro-CAD in the new Ple4Win manual.


Request 2:
Please add the missing documentation about the element length from the old theoretical manual of PLE-micro-CAD in the new Ple4Win manual.
I have attached a PDF in this message about this old documentation.


Request 3:
Add extra loadfactors columns in the internal overpressure [PRESS] input table in Ple4Win, so that the loadfactor 1.25 can be manually changed to a higher value in case of the NEN 3650-2 (i.e. in (valve)stations) or in case of the Pipeline Handbook of Rotterdam. Now the factor (in case of the NEN 3650-2) is internally increased in the Ple4Win program by 1.25 for the internal design pressure only. If the General analysis method is used, the loadfactor of the LOCASE table is used (conform NEN 3650-2 it is 1.15), which means that the NEN 3650-2 factor 1.15 instead of 1.25 is used for the hoop stress (BC 2), which is not correct for the internal design pressure only. Try to standardise this in the PRESS input table by adding the loadfactor columns only for the hoop stress (BC 2), which is used in the General and NEN 3650-2 analysis method. For other loads in combination with the internal overpressure (i.e. BC 4) the LOCASE table loadfactor should always be used. In the output table two columns of PRESS values included the loadfactor should be presented: one used for BC 2 in output table LOADATA in the PRESS column and one used for BC 4 in output table INTFOR in the F-AX column.

Another way is to increase the LOCASE loadfactors input table with an extra column for the internal design pressure only (BC 2). Please make loadfactor jumps at Idents possible with multi-rows (so that the current 1-row input table is replaced and consistent with other input tables in Ple4Win) in the LOCASE table and by adding two columns for every loadcase.

According to NEN 3650-1:2020 the deadweight has also a large influence in pipe-soil friction for large diameters. This is missing in the formula, see green box below. The additional deadweight value has a positive or negative influence in the pipe-soil friction.

I know you can take this manually into account by using the CFA factor in the F input table. I can't check if the Soil Model Wizard also generates for CFA = tan(delta) in the F (longitudinal friction) table. This isn't mentioned in the help file at: https://help.ple4win.nl/index.html?longi...iction.htm

Another issue is given below that peat is set to zero. This can't be the case, because it has an angle of internal friction of 15 degrees and has an adhesion value. I know the value is low, but not zero. So, setting the pipe-soil friction for peat to zero is incorrect in the Soil Model Wizard.
