Flat Plate Displacement in Bolted Joint
Flat Plate Displacement in Bolted Joint
(OP)
I am trying to determine the displacement (at the center of the end plates) for the end plates of a bolted joint. The image should give you an idea of what I'm after. As you torque the bolts down the plates deflect towards each other (more on the edges than in the center of the plate). I am assuming for the sake of calculation that the meat of the sandwich is rigid and fixed. I looked through Roark's and the interwebs without any luck, and I have already done the FEA which matches what I've measured empirically. For the sake of argument we can ignore that there are stacked end plates in the drawing attached.
I'm looking for some formulas that will allow me to determine the displacement of the end plates so I can determine how thick those end plates need to be to avoid displacement at a certain bolt torque. Make sense?
Any idears?

This model should get you quite close to where you want to go.
A special attention should however be devoted to corner bolts, as the corner of the plate could deflect more.

all round, it looks like a plate loaded by moments along the perimeter, ... no?
