Maximum stresses at inner face of wall per element (material non-linear analysis) (Output Table)

Table description:

The output data table INSIGM provides a list of maximum (elastic) stresses at the inner wall face over the circumference of the cross-sections where calculations have been performed.

The stresses collected in this table are the result of all internal and external loadings on the cross-sections due to the overall and the local cross-sectional behaviour of the pipeline.

The stresses provided are the absolute maximum values over the 144 points over the circumference of the cross-section together with the sign of that extreme value.

Detailed stress data of the last data line of the table are contained in the additional output data table INSIG.

The table acts in an accumulative way if the unlock option is used.

Each time Design Function 6.2 (General, Material Non-linear) is restarted, the result data are added for the cross-sections specified in table SECTION with basic data not contained yet in CSGEN/CSLOAD. However, if Design Function 6.2 (General, Material Non-linear) is set back, all data in table INSIGM are destroyed and the table gets the EMPTY status.

The loadcase name and the phase number, if applicable, are shown in the table heading.

Explanation of the abbreviations in the stress-component mnemonics:

Each stress or strain component mnemonic contains 3, 4 or 5 items :

1.

s:

(normal) stress component

 

t:

shear stress component (tau)

 

e:

strain component

 

2.

I:

stress / strain at inner wall face

 

M:

stress / strain at mid wall location

 

O:

stress / strain at outer wall face

 

3.

X:

stress/strain in longitudinal direction (parallel to x-axis of element)

 

F:

stress/strain in circumferential direction (perpendicular to x-axis)

 

Eq:

equivalent stress/strain according to Von Mises' theorem

 

1:

first principal stress/strain (near axial direction)

 

2:

second principal stress/strain (near circumferential direction)

 

Z:

shear stress in X-F plane (plane of pipe wall)

 

12:

maximum shear stress (in Mohr's circle, excluding zero stress perpendicular to pipe wall)

 

max:

maximum shear stress (in Mohr's circle, including zero stress perpendicular to pipe wall)

 

12max:

maximum principal stress/strain over wall thickness

 

12min:

minimum principal stress/strain over wall thickness

 

4.

-E:

elastic stress/strain component

 

-P:

plastic strain component

 

-S:

total (= elastic + plastic) strain component excluding Poisson and stressless strain

 

-T:

total (= elastic + plastic) strain including Poisson and stressless strain

 

and for the *M(ax) tables:

5.

-M :

maximum of stress/strain over circumference of cross-section

 

Example:

 

 

eMX-T-M = maximum of total strain in longitudinal direction at mid wall location.

Info Item 2 is not applicable for the check stress/strain tables, because these tables contain maximum values over the wall thickness.
