Ple4Win´s Special modules (L)
The visualisation module (X1) shows a 3D representations of the configuration and the calculation results.
The soil model wizard converts laboratory soil data into specific pipe-soil mechanical data.
Both the small angle- (N) and large angle- module (L) allow non-linear geometric calculation of the displacements, internal forces, and related soil and support reactions, based on equilibrium of the external load system on the deformed pipe structure.
This module redistributes local ring ovalisations, based on harmonic dependent wave length.
Using the non-linear geometric section module, limited bend angle and altered (bend) stiffness due to ovalisation are taken into account.
With the non-linear material module, yielding of the (steel) material is taken into account (only in a last phase or one phase only)
In case of outbreak of the pipeline due to (upheaval) buckling, the soil mechanical data are adjusted due to the displacement of the pipe.
