As mentioned, this method can be used on a plate with pinned edges. The
boundary conditions can then be formulated as:
The method consists of a Fourier serial development of an arbitrary load like this:
We can now express the displacement function as as a Fourier series:
When the displacement w(x,y) is known, inner moment, shear forces and stresses can be calculated. This calculation method has quick convergence for load distributions that covers the entire plate. And the method is well suited for solution on computers.
