Moment/stress caused by the bending of bushing flange

[hootrpootr]

Hello,

I'm checking the bending of a bushing flange, where a high axial force (along axis of bushing) is essentially pulling the bushing through a hole and causing the flange to "kick up". How would I determine the moment and stress caused by the load?

I'm thinking, what if I convert the pressure to a distributed load "w" (P/A x circumference) and treat the distributed load as acting over a thin section of thickness "b"? Then the moment would simply be wL^2/2 and the stress would be My/I, where y is t/2.

Apologies for the crude excel sketch. Any thoughts are appreciated!

Your critical section is the bushing wall. Method of stress calculation is correct with the addition of stress from axial load. (P/A ± M*t[sub]w[/sub]/I[sub]w[/sub])
