Maximum radial deformations of pipe cross-section (material non-linear analysis) (Output Table)
Data description/Result options:
Number of element where deformation calculations have been performed at mid cross-section
Maximum radial deformation of pipe wall due to soil reactions
Maximum radial deformation of pipe wall due to ovalisation of bend caused by bending moment
(Undefined if ELEM is not a bend element.)
Elastic part of maximum total radial deformation of pipe wall
Plastic part of maximum total radial deformation of pipe wall
Maximum change of diameter (in %) due to loads on cross-section
(The outer diameter is used.)
Maximum total radial deformation of pipe wall due to all loads
Elastic impression of the soil at 50 % of 'horizontal' bearing capacity ¹
(RG is 50 % of RH or (RVS+RVT)/2 whichever has the lowest value, KLG is KLH or (KLS+KLT)/2 whichever has the lowest value, so -M means 'Minimum' in stead of 'Maximum' here.)
'Horizontal' bedding constant (soil stiffness) ¹
(KLG = KLH or (KLS+KLT)/2 as long as WTOTAL is less than or equal to RG/KLG-M.
If WTOTAL > RG/KLG-M, KLG decreases.
KLG is a bilinear soil spring.)
Maximum axial buckling strain as a percentage of the critical one
Maximum percentage of critical strain due to external pressure
¹ These quantities are reported only if the Soil Ring-Stiffening Option is Applied. The bilinear soil spring KLG is attached to those points of the cross-section which move to the outside due to the ovalisation. The average soil parameters are taken, so without uncertainty factors. The maximum soil resistance (RG) taken into account is 50 % of the lowest bearing capacity.
