Plate Deflection
Plate Deflection
(OP)
I am applying a load to the center of a plate that is stiffended by beam elements (see attached sketch). Assuming the beams are rigid, how can I calculate the deflection if the load is applied at the center of the plate.
The plate is seal welded to the rigid beams. Thanks.

if not define a/b (long side/short side).
also load and thickness

I realize that this sketch may not be the whole story though.
RE: Plate Deflection
ω = α Pa2/D
Values of α are give for various b/a ratios (length/width). When b/a = 2, 3, ∞, α = 0.1651, 0.1690 and 0.1695 respectively.

RE: Plate Deflection
The introduction to chapter 11 specifies that the tables are based on several assumptions, including that the maximum deflection is not more than one half of the plate thickness. If your deflections are larger than this, you will need to consider another approach. There is a table on page 452 for large deflections of rectangular plates, but the for uniform loads, not concentrated.
