reducing elbow modeling - 02/07/08 08:04 AM
Hi everybody
How can one model a "reducing elbow" in CAESAR II? Is that ever possible?
Thanks

Use the average diameter and wall thickness, and the actual bend radius. There is no reducing elbow element in Caesar II.

As Loren stated, you can't model this directly in c2. You do realize this isn't a "Code Fitting", so any SIFs computed using Code Equations should be questioned. The elbow flexibility won't be exactly right either.
1) Average properties is one approximation.
2) You could also model two bends (say 2 45s instead of 1 90) and change the properties on the 2nd. This is more difficult because you have to determine the two tangent points.
