Kernel Module

Functional characteristics of the KERNEL (K) module.

Design and analysis of  a 3D, buried or unburied, pressurized or pressure less transport pipelines.

Input facilities:

a.        Configuration conditions

       3 dimensional pipeline axis configuration (PIPE and BEND elements)
       various end boundary conditions (FREE, FIXED and INFINite)
       linear elastic external supports (GLOBAL and LOCAL coordinate systems)
       ground and groundwater level


b.        Pipeline conditions

       linear elastic pipe material variable along pipeline axis
       variable diameter along pipeline axis
       variable wall thickness along pipeline axis
       pressurized toroidal shell bending stiffness properties


c.        Soil conditions

       non-linear elastic soil deformation behaviour
       direction dependent lateral soil stiffness and ultimate soil support properties variable along pipeline axis
       soil friction stiffness and ultimate soil friction properties variable along pipeline axis
       uncertainty factors for easy soil parameter variation
       3 dimensional soil settlements and deformations


d.        Operational conditions

       internal/external pressure variable along pipeline axis
       temperature variations, variable along pipeline axis
       deadweight variable along pipeline axis
       additional point loads (GLOBAL and LOCAL coordinate systems)
       overall and component load factors


Output facilities:

       generated and compiled input data overviews
       internal forces and bending and twisting moments in the pipeline
       displacements and rotations along the pipeline axis
       soil reaction forces acting on the pipeline along its axis
       external support reactions
       bend stiffness and stress concentration factors
       detailed pipe/soil model iteration behaviour results.
       selected print facility
       selectable print on file facility
