Main window ribbon: Analysis > SIFs > SIFs @ Bends

Opens the Bend Stress Intensification Factors dialog box. You can calculate stress intensification factors (SIFs) for various bend configurations under different codes.

You can compute bend stress intensification factors for the following:

  • Pipe bends without any additional attachments. These calculations are done according to the piping code being used.

  • Mitered pipe bends. These calculations are done according to the piping code being used.

  • Pipe bends with a trunnion attachment. These calculations are taken from the paper “Stress Indices for Piping Elbows with Trunnion Attachments for Moment and Axial Loads,” by Hankinson, Budlong and Albano, in the PVP Vol. 129, 1987.

To begin, specify a new job name in the New Job Name Specification dialog box or click Browse to navigate to an existing job file.

All CAESAR II analyses require a job name for identification purposes. After you create or open a job, you can enter input data and then define, analyze, and review your data.

The Bend Stress Intensification Factors dialog box consists of two input tabs: the Bend Tab and the Trunnion Tab.

In most cases data that does not apply is left blank. For example, to review the SIFs for a bend that does not have a trunnion, do not enter values for the trunnion-related input fields on the Trunnion tab.
