Kernel Module
Contents
Functional characteristics of the KERNEL (K) module.
Design and analysis of a 3D, buried or unburied, pressurised or pressureless 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
•pressurised 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
•print facility for individual input- and output tables, possibility to only print groups or extreme values
•multiple tables print facility using a dedicated specification screen, table sequence can be adjusted and full table data/extrema’s only can be selected per table
