Snap ring force
Snap ring force
(OP)
How can I calculate the radial squeezing force of a snap ring or retaining ring? I've done some searching, but I can only find info on dimensions and thrust loads.
Since it's a spring, I'm assuming there's a formula to calculate the force.

Not the ultimate in snap ring design but it might help you
get an idea of the force.

I'm trying to calculate the force required to close the seam gap on a pipe rolled from a flat plate.

In desertfox's supplied equations, the only material property considered is the modulus of elasticity, which is constant for steel. Why isn't the tensile strength of the steel a factor? Wouldn't a higher strength steel make for a stronger spring?

M/I=E/R=s/y should cover it. R is the extra bend due to M, not the geometrical shape of the ring. You'll need to integrate along the circumference of the snap ring, depending on the loading condition. I think your design approximates to a pair of opposing tangential forces, pretty much, so the bending moment diagram is fairly straightforward.
