Bending Of Rectangular Plates

The theory of bending of rectangular plates is beyond the scope of this text and will not be introduced here. The standard formulae obtained from the theory^ however, may be presented in simple form and are relatively easy to apply. The results for the two most frequently used loading conditions are therefore summarised below.

7.15. Rectangular plates with simply supported edges carrying uniformly distributed loads

For a rectangular plate length d, shorter side b and thickness t, the maximum deflection is found to occur at the centre of the plate and given by qbA

the value of the factor a depending on the ratio d/b and given in Table 7.3. t S. Timoshenko, Theory of Plates and Shells, 2nd edn., McGraw-Hill, New York, 1959.
