Let’s say I have an irregularly shaped bearing with a cross section that looks like the angled surface of a conical frustum, shown below.
If a bending moment is applied which causes the inside diameter to ‘cave outwards’, how would I perform a static loading failure analysis to see at what bending moment the shape would cave outwards? How would I determine the second moment of area and distance from centroid values required to apply the bending stress formula sigma = My/I? Or is there a manufacturing method in the form of some sheet metal bending formula that would be more helpful in looking at failure mode in a cylindrical cross section instead of a planar one.
EDIT: The end goal is to have the curved surface completely vertical, as if it was the surface area of a rod. If there is an easier method of calculating the forces required, let me know!
