Calculation for Deflection of a Ring under Compression
Calculation for Deflection of a Ring under Compression
(OP)
I am looking for the formula for deflection of a ring under point load. I have ID, OD, E, G, and the load. If anyone has it or can point me in the right direction I would appreciate it.

Google the subject under this topic heading. There is lots of websites that probably have the exact equation needed.

M=m1-(P/2)r(1-cos@)The partial derivative with respect to M1 would be the slope at the west position is zero due to symmetry and the partial with respect to P is the vertical displacement, your problem. After all this I get
y=Pr^3(pi/4-2/pi)

I left off EI in the denominator; it should read:
y=Pr^3((pi/4-2/pi)/EI
