Rectangular Plate Uniform Load Simply Supported Equations and Calculator


Rectangular plate, uniform load, simply supported (Empirical) equations and calculator

Since comers tend to rise off the supports, vertical movement must be prevented without restricting rotation.

Symbols used:
a = minor length of rectangular plate, (m, in)
b = major length of rectangular plate, (m, in)
p = uniform pressure loading, (Pa, lbs/in2)
v = Poisson’s ratio
E = Young’s modulus, (N/m2, lbs/in2)
t = plate thickness, (m, in)
s m = maximum stress, (N/m2, lbs/in2)
ym = maximum deflection, (m, in)

No ....the plate is simply supported along the edge associated with length "a" not "b".

Sorry, I do not understand why this formula is not symmetric for a and b. If you would exchange the values for a and b, the deflection should be the same I think?
