Enter True to include the ASME Sec. VIII Div. 2 Table AD-560.7 pressure stress indices in a fatigue analysis. This option should only be used if you are performing a fatigue analysis. Check ASME VIII Div.2 paragraph AD-160 to see if the fatigue effect needs to be considered. The pressure stress indices are used for estimating the peak stress intensity due to internal pressure.
-
Peak stress intensity due to external loads is included in the analysis when values are entered in Nozzle Kn and Nozzle Kb.
-
For normal (elastic) analysis, do not select this option or enter values in Nozzle Kn and Nozzle Kb.
-
The software does not perform the complete fatigue analysis of Section VIII Div.2 Appendix 4 and 5 rules. Instead, the value of peak stress intensity is reported for fatigue effect comparison.
