Strain of bending ring perpendicular to axis - statics question
Strain of bending ring perpendicular to axis - statics question
(OP)
Hi all,
I've been trying to figure out how to calculate the strain acting on a ring (van stone flange in this case) perpendicular to its axis. See the picture for a diagram of the testing setup.
The van stone flange is placed on the bend bar and four bolts attach the flange to the plate. The bolts are then torqued and the flange will bend. My question is how do I calculate the strain applied to the flange when it is displaced a certain amount caused by the torque?
Any and all help will be great! Thanks,
Krevan

so how does a plate like this deflect ? well, I'd look at a 1/4 of the problem, with symmetry constraints at the ends a force applied, and reacted. Roark might have something, else you have to solve the doubly redundant problem.
the redundant (unused) holes in the flange are a minor, local, issue ... shouldn't significantly the global problem.
another day in paradise, or is paradise one day closer ?

Note however that for the above to be fully true the loads (bolt holes) should be placed midway of ring width. Otherwise you'll also have some twisting that is also treated in the references above.
