I'm trying to understand how the Bourdon effect is incorporated in the software. So, I modelled a simple pipeline which consists of a bend with two straight runs. I analyzed the model once without enabling the "Bourdon effect" option and another time with enabling this option. I couldn't find any difference in the stresses or displacements.
I was expecting to find higher stresses on the extrados of the pipe elbow however that was not the case.
I attached a PDF showing the model geometry and loading, and the results from both cases.
I have a follow-up question. I could not find any documentation on how the program includes the Bourdon effect. Does it do it at the displacement level or does it add moments? Is there an equation that I missed? Thanks.
