Moment Distribution In bent pipe modelled with Shell 181 element

[Hoodyz]

I am modelling a pipe bent on a reel and studying the stress and strain distribution, I have obtained a solution to the model, but I am having difficulties getting the bending moment in the pipe so that I can validate if the moment at buckling is same with code provisions. The pipe was modeeled with Shell 181 element for large deformations.


Please does anyone know how I can get the Moment distribution in a bent pipe.

Thanks.
