Calculating Square Flat Plates
Cross section size
A = L2
Square flat plate supported at all four edges and a load distributed uniformly over the surface of the plate.
Max. stress
Deflection
Square flat plate with all edges firmly fixed and a load distributed uniformly over the surface of the plate.
Max. stress
Deflection
Square flat plate with all edges firmly fixed and a uniform load over small circular area at the center.
Max. stress
where:
r0 = radius of area to which load is applied. If r0 < 1.7t, use rs where rs = √(1.6r02 + t2 ) - 0.675t.
Deflection
Square flat plate with all edges supported above and below, or below only, and a concentrated load at the center.
Max. stress
Deflection
