CAESAR II Version

Specifies the staunchion outside diameter. This is an optional entry, used only if there is a staunchion or dummy leg attached to the bend. If you define Staunchion OD, you must also define Wall Thickness.

Typical units (depending on your unit system):

  • in

  • mm

  • cm

The stress intensification factors for dummy legs is from the paper: "Stress Indices for Piping Elbows with Trunnion attachments for Moment and Axial Loads.", PVP Vol. 129, 1987.

The equation (1.7)i = (C2)(K2)is used to get from the calculated (C2) coefficients to the stress intensification factor (i). If you do not define a value for the stress concentration factor, it defaults to 2.0.
