Plate deflection and stress formula

Plate deflection and stress formula

Plate deflection and stress formula

(OP)
I am looking for a formula to determine max deflection and stress of a plate (round or square) that is simply supported in the center (round support) and a uniform load over the whole surface. Can anyone point me to a good example?
Thanks.

roark ?

another day in paradise, or is paradise one day closer ?

RE: Plate deflection and stress formula

For a circular plate you can obtain a solution by superimposing, on a simply supported plate, a uniform load and a point load of opposite direction and same resultant.
For a square plate the same can be done, but you need the solution for a plate supported at the corners only, that you can find here and here.

Thanks, metengr's link was close, but there was a better match to my situation Link
Roark's Formulas for Stress and Strain would work as well for just about any situation, adding to my collection.

RE: Plate deflection and stress formula

No.

That web page assumes a ring support (NOT a simple single support at the center of a round plate as in your original statement).
After entering a round 10 unit diameter plate with a 2 mm thickness, it told me the edges of the plate deflected more than the original plate thickness under a 100 load.

Not sure I'd trust it.
