Hello,

I would appreciate some help in this matter.

What are the considerations of Coade for the new equations of Sustained stress in paragraph 320 of ASME B31.3 2010?

More accurately, the Code now is asking to include axial and torsional SIFs for computing sustained stresses in that paragraph. Are they included automatically by CaserII for pipe
elements enlisted in Appendix D or not?

The Code also says is designer's responsibility to determine them (axial and torsional SIFs) for pipe elements outside Appendix D, such as crosses...
in reality this implies to establish the four SIFs (in-plane, out-of-plane, axial and torsional for them...any reference for this?
