Miter Bend SIF

Miter Bend SIF

Dear Friends,

I'm trying to perform stress analysis of high temperature(T=510 C) ducting with 2600mm in diameter and 10mm thk. This duct includes several miter bends and expansion joints based on basic design. The software I uses is CAESAR II. But I know SIF and K factors are not calculate correctly in CAESAR II for D/t>100. I have two questions:
1-Does FEPIPE(for Paullin group research ins.) include SIF and k factor calculation for miter bend?
2- If I want to use ANSYS software to calculate overstress of miter bends, what data I should read from CAESAR and use in ANSYS?
