Dear All, 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.
