This issue is handled in van Rijn et al, "Deflection and maximum load of
microfiltration membrane sieves made with silicon micromachining," J
MEMS, 6(1), 1997.  They address rectangular and square membranes with
residual tensile stress undergoing large deflections.

Because the incorporation of large deflections makes the problem
nonlinear, a number of assumptions need to be made to extract a simple
equation of deflection.  Different authors have obtained slightly
different solutions, and analysis of the problem from strain energy
principles can be very time-consuming.  If you are modeling a
microfabricated device, it may be easier to use FEM to generate
numerical solutions.

I agree with Shay Kaplan's earlier comment: Timoshenko does deal with
diaphragms, in Chapter 9 of "Theory of plates and shells."  Large
displacements in plates = strain in the middle plane = diaphragm
effects.

Also, Giovanni's book is available in MIT's library (libraries.mit.edu).
