Cross section size
A = L 2
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:
r 0 = radius of area to which load is applied. If r 0 < 1.7t, use r s where r s = √(1.6r 0 2 + t 2 ) - 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
