Does anyone know where I can find the SIF for a cross or how I can calculate it?

Mike,
A cross is not a B31.1 fitting so you won't find published SIF's for crosses.

Dear Mike,

It strongly depends on the D/d ratio whether one side of the cross will affect the opposite side. We are using FE/Pipe to analyse these geometries. Based on my experience, the D/d must be close to one to find an interaction between the two sides of the cross.

You could send me geometry data and we will have a look at it.

All the best,
