Rectangular Plate Circular Load Equation and Calculator
Rectangular plate, circular concentrated load at center, clamped edges (empirical) equation and calculator.
The load is assumed to act over a small area of radius e.
Symbols used:
a = minor length of rectangular plate, (m, in)
b = major length of rectangular plate, (m, in)
P = Concentrated load, (N, lbs)
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)
