Detailed unit check stresses according to mohr, tresca mises or uniaxial, using predefined weighing factors (Output Table)

Data description/Result options:

ANGLE:

Location at circumference where calculation have been performed

(Measured in positive sense around x-axis from y-axis.)

Sp/0.91ReT:

Hoop stress unit check stress

Info For historical reasons the column heading is reported as Sp/0.91ReT, whereas the actual result is calculated as 1.1Sp/ReT

Sv:pm/Re:

Primary unit check stress due to primary loads

Sv/f(Reb):

Total replacing unit stress due to all occurring loads

S-IND:

Stress class indicator (see below)

 

Info The number of rows is 48 (each 7.5 degrees).

Description of unit stress classes

The unit check stresses are the calculated check stresses Sp, Sv:pm, Sv, divided by material factors and (a combination of) yield stress Re and/or ReT.

The unit stress indicator S-IND refers to the maximum corrected check stresses Sp, Sv:pm, and Sv and provides a quick overview on the occurring stress class:

blank

maximum check stress ≤ 40% of applicable limit stress

Bug678_1

maximum corrected check stress > 40% and ≤ 60% of applicable limit stress

Bug678_2

maximum corrected check stress > 60% and ≤ 80% of applicable limit stress

Bug678_3

maximum corrected check stress > 80% and ≤ 100% of applicable limit stress

Overstressed:

maximum check stress > applicable limit stress
(In this case one or more of the unit check stresses is greater than 1 which is not allowed according to NEN 3650.)

The stress correction factor is defined as the factor by which the calculated stresses Sp, Sv:pm or Sv have to be multiplied before checking the result against the yield stresses ReT, Re or Re+ReT.

Sp is checked against yield stress ReT

Sv:pm is checked against yield stress Re

Sv is checked against the sum of yield stresses Re and ReT
