Enter a value, typically between 1 and 3, for stress concentration due to weld quality and dimensions in the immediate vicinity of the weld. The stress concentration factor:
-
Accounts for peak stresses - local stress risers in the immediate vicinity of vessel welds due to factors such as sharp corners and lack of fillet weld radii. Peak stresses are considered in fatigue analysis.
-
Applies to the stress calculations in the vessel and the nozzle on both the inside and the outside of the vessel.
-
Is used in pressure stress calculations in the vessel on both the inside and outside of the vessel.
This value is only available for ASME material when PD5500 Annex G? is not selected.
