How to set the SIF for Caesar II elbows
Thread Content
When analyzing large-diameter, thin-walled pipes now, it is necessary to define the SIF for elbows; I’m not sure where exactly this should be set Thank you to everyone for helping to provide solutions! This post was last edited by fanking on 2009-2-4 12:32.]
It seems that in the Configure settings, one needs to allow the definition of elbows; after creating the elbow, select TEE&SIF to define it
What was said on the 2nd floor isn’t correct, right? The most reliable method for determining the SIF of large-diameter thin-walled pipes using tees is to carry out modeling and calculations with Ansys or FE/PIPE; this is indeed the most accurate approach. The Analysis module in CAESARII includes an SIF&Bend option that allows for the calculation of the stress increase factor, which can then be incorporated into the input files for the piping system. However, based on my experience, the stress increase factors calculated by Ansys and CAESARII can sometimes differ significantly, even by several times. Therefore, I recommend using Ansys or FE/PIPE for more accurate results. If you’re free, moderator, give me your QQ so we can communicate privately; I also often use large-diameter thin-walled pipes.
