Bending stress in pipe_2d
Please see the picture. I need to find the bending stress for that profile.
Its hollow tube dia= 38 mm, 4 mm thick. its is acted with udl of 500 N/m2 on its outer surface.
How can I estimate the bending stress, deformation. Assume it as mild steel with E = 200 Gpa, poission ratio = 0.3.
I am trying to validate this with FEA in 3d.
Kindly share your ideas. Thank you in advance.

It's statically indeterminate so you can use a method for those types of problems. Maybe Castigliano's.
Or, you could get upper and lower bounds by treating the bends as rigid and pin-jointed. Then it's an easy simply supported beam problem.
