Bending Moment for Solid Circular Plate
Bending Moment for Solid Circular Plate
(OP)
Does anyone have a formula for the bending moment for a circular plate with a concentrated load in the center. I have a few books on this issue but they are not clear. I also have Ram Advanse which can do a shell analysis. I can only model a square plate. Any tips will be greatly appreciated.

For a simply supported plate the radial moment is
Mr=P(1+ν)log(R/r)/4π and of course it goes to infinity at the center.

but remember this is a plate solution, watch for large displacements, > 0.5t, which cause appreciable stresses on the mid-plane (not accounted for in plate analysis).
