    OK, thank you sincerely. Maybe you are right, but I still have to find a time to compare it with the finite element method. Only in this way can I convince myself. ha-ha..

    SIF of thick wall bend

    Thank you, friend! But your formula should be in B31.3. However, don't you think it's strange? Why is SIF of thick pipe elbow equal to 1.0? We know that the straight pipe is calculated based on the beam element, but the elbow is inconsistent with it. The elbow will produce non-circular...

    SIF of thick wall bend

    Hi everyone!When I used CAESAR II to calculate a thick wall pipe,for instance,406.4x59mm,I found that the SIF of bend was 1.0,this is consistent with the formula in B31.3. But what puzzles me is why the bend SIF with a thick wall is 1.0 itself，or why this bend has no SIF ？Please help me,thanks a...
